Psychology Research Methods Weekly Practice
« on: January 14, 2018, 02:18:22 pm »
+27
 Each week, I will upload a text and questions aimed at helping you gain proficiency in research methods. It is ok if you aren’t sure or confident – I would highly encourage you to have a shot and learn something. I really hope that this thread is used by people with a broad range of abilities. Ideally, the difficulty/complexity of the questions will increase as the year goes on. Towards exam prep time I may post 10 markers here as  well.

     1st (day of questions being posted) to 3rd day: reply with your answers (it’s ok if you have no idea where to start for some of them – do what you can)
     1st to 4th day: Find answers that others wrote and you think are high quality (eg. 1.  Quote UserB    2. Quote UserA     3. Quote UserC ). Please also say why you think it’s a great answer.   This time can also be used to refine your answers, by quoting your previous post and/or relevant feedback and indicating what you are now changing your answers to. It can also be used to provide and query feedback.
     5th and 6th day: Group discussion on the optimal answers and agreement on answers that should make it into the solutions guide
     7th day: I will compile the exemplar answers into a solutions guide and post it here

This thread is designed for aspiring and current psych students (1/2 or 3/4) to improve their knowledge but feedback is welcome from previous students :).

WEEK 1 QUESTIONS

Dr John Citizen suspects that blue tablets are more effective than white tablets and conducts an experiment to test this. He asks for friends and family between 18-30 years of age without a pre-existing medical condition, to volunteer, and 60 agree to participate. He splits the participants into two groups of 30. Group 1 is given blue PainGo tablets while Group 2 is given white PainGo tablets. Both tablets have the exact same composition aside from the blue dye agent in Group 1s tablets. Over the course of six months, the participants logged their levels of pain on a scale of 1 to 10 before, and 1 hour after, taking a PainGo tablet when/if they experience a headache. Dr Citizen analyses the data and finds that the mean reduction in pain was 1.2 for Group 1 and 3.2 for Group 2. He also finds that the standard deviation for Group 1 was 9.2 whereas for Group 2 it was 11.6. After analysis, Dr Citizen uploaded the data and findings, then shared the access link with all participants.

1.   What is the aim of the experiment? (1)
2.   Write a suitable research hypothesis (1)
3.   Operationalise the dependent and independent variables (2)
4.   What experimental design was used? (1)
a.   List one advantage of this design (1)

3.Operationalise the dependent and independent variables (2)
4.What experimental design was used? (1)
a.List one advantage of this design (1)

8.Comment any ethical concerns surrounding the experiment (2)
9.Can Dr Citizen’s findings be generalised? Explain. (2)
10.Which group showed greatest variation in results? (1)


1. The aim is to investigate if blue tablets are more effective than white tablets in reducing pain levels.

2. It is hypothesized that adults who take blue tablets will have a greater reduction in pain compared to adults who take white tablets.

3. IV - blue or white colour of the PainGo tablet.
DV - recorded level of pain on a scale from 1-10 before and one hour after taking the PainGo tablet

4. Independent groups
a) An advantage of independent groups is that order effects is controlled.
Quote
For 4a it isn't a good idea to talk about order effects being controlled as they aren't relevant to an independent groups design.
Edit: An advantage of independent groups is it’s less time consuming than repeated measures and matched participants as participants are just randomly allocated and the experiment is repeated once.

5. Limitations to this experiment include results recorded are assumed to be accurate answers and participants may give false answers or fake their results.
Quote
For 5 I'd like you to go deeper. It's true that participants might give inaccurate answers, what could cause that to happen?
You later (correctly) talk about how conveniance sampling creates a less representative sample than random sampling. Therefore, conveniance sampling is a limitation. I would recommend you discuss sampling rather than accuracy being assumed, as a) it shows off your psych knowledge more b) it's dangerous to talk about what the researcher's assumptions are - because we don't really know
Edit: Limitations include convenience sampling which can cause experimenter bias whilst conducting the experiment. Another limitation includes participants giving false results due to social desirability.

6. Experiment can be improved by using a different sampling method such as random sampling, which is more representative of the population than convenience sampling. It can also be improved by using an automatic logging system such as an app to make it easier for participants to log their results.
Quote
For 6 I like the first part of your answer but we don't know what logging system was used and so can't really comment on that. Hint for an alternative: something other than sampling procedure that increases the ability to generalise results.
Edit: Experiment can be improved by using a different sampling method such as random sampling, which is more representative of the population than convenience sampling. It can also be improved by using a greater sample size such as 50-100 people as this means the experiment increases in its ability to generalize back to the population.

7. Dr. John Citizen collected quantitative data.

8. Dr. Citizen did not receive informed consent as his participants were not told about the risks or purpose of the study beforehand and written consent was not obtained. Dr. Citizen also did not properly debrief his participants as he did not explain the true nature of the study or correct any mistaken beliefs as well as offer counselling if necessary, although he did report his findings to the participants via a link.
Quote
For 8 I'd caution against saying that something did not happen just because it wasn't mentioned.     To clarify the scenario: All partipants received all of the data
Edit: Dr. Citizen may not of conducted informed consent procedure as his participants were not mentioned to be told of about the risks or purpose of the study beforehand and written consent was not mentioned to be obtained. Dr. Citizen also did not appear to debrief his participants as he doesn’t seem to have explained the true nature of the study or correct any mistaken beliefs as well as offer counselling if necessary, however all participants received the experimental data.

9. Dr. Citizens findings can not be truly generalized to the population. This is because convenience sampling was used, which is not representative of the wider population.

10. Group 2.

10.   Which group showed greatest variation in results? (1)

1. The aim of this experiment is to observe whether the colour of PainGo tablets has an affect on levels of pain experienced after consuming them.
2. It is hypothesized that adults who take a blue PainGo tablet will have a greater reduction in perceived pain levels one hour after taking the tablet, as compared to those who took a white PainGo tablet.
3. The independent variable is the colour of the PainGo tablet, either white or blue with the addition of a dyeing agent.
The dependant variable is the difference in perceived pain levels before and after taking the tablet, measured on a scale of 1-10 immediately before and subsequently an hour after consumption.
4. Independent groups
4a. Avoids order effects such as practice or fatigue.
5. One limitation might be the self-reporting of pain levels. Validity of the participants' responses may be questioned because of cognitive biases, exaggeration and lack of standardization. Another limitation might be the use of an independent groups design. The individual differences in participants are an extraneous variable; differing pain tolerances or attitudes towards medication between participates may affect their reporting on the effectiveness of the tablet.
6. Individual differences as an extraneous variable can be eliminated by using a repeated measures (or other) study design. By using the same sample for the control and experimental conditions, individual differences are unlikely to be a problem. However, order effects may be difficult to control. Another improvement could be the sampling method. Convenience sampling is not representative of the population.
7. Quantitative
8. There is no mention of debriefing in the research scenario, which is unethical because the participants are left not knowing the nature/intention of the study, nor have any information regarding professional help should that need it. It is mentioned that the results are shared with all participants via an online upload link. It is not mentioned whether participants' confidentiality was protected. If all participants are able to see results of others', especially with names or other private information, it is a violation of the participants' confidentiality and privacy.
9. No, the results cannot be generalised because the convenience sampling method does not allow for an accurate representation of the population (18-30 year old adults). Statistical significance also has not been considered.
10. Group 2

I didn't forget! Woohoo.
This was surprisingly challenging after a year of no psychology. I mentioned statistical significance but I've heard it isn't too important in this study design. Eeeep. I tried lmao.

This was surprisingly challenging after a year of no psychology. I mentioned statistical significance but I've heard it isn't too important in this study design. Eeeep. I tried lmao.

For 4a this is true, but in my experience is probably less likely to be accepted than other responses such as "independent groups designs are time and money effective". It might be worth talking to your teacher about this - they're the ones setting your SACs. Note: matched participants also avoids order effects, so this advantage doesn't apply in comparison to that.

For 6 I'd be cautious about use of the word "eliminated" anywhere in psychology. I would suggest using "accounted for" rather than "eliminated by". You have acknowledged the drawbacks of repeated measures (good scientific thinking to do that btw) so you already know that it's not necessarily reducing the impact of extraneous variables. I'd suggest a different advantage (hint: maybe one that also reduces the effect of participant variables through the experiments design)
I'm also assuming "study design" is a typo caused by over-exposure to VCAA  :P

For 8 something not being mentioned (to you the reader, I think you it's a different story if something wasn't mentioned to a participant) isn't unethical. It would be unethical if debriefing didn't occur - I suggest tweaking your wording if you want to include this in your response.

For 9  I wouldn't bring up statistical significance. You don't even have to know p values anymore.

Here, I've only given you things to adjust, but I do want to point out that I really liked some of your responses (I will tell you which ones, but not just yet) and you haven't made any content knowledge mistakes. You've shown great content understanding thus far :)

WEEK 1 QUESTIONS

Dr John Citizen suspects that blue tablets are more effective than white tablets and conducts an experiment to test this. He asks for friends and family between 18-30 years of age without a pre-existing medical condition, to volunteer, and 60 agree to participate. He splits the participants into two groups of 30. Group 1 is given blue PainGo tablets while Group 2 is given white PainGo tablets. Both tablets have the exact same composition aside from the blue dye agent in Group 1s tablets. Over the course of six months, the participants logged their levels of pain on a scale of 1 to 10 before, and 1 hour after, taking a PainGo tablet when/if they experience a headache. Dr Citizen analyses the data and finds that the mean reduction in pain was 1.2 for Group 1 and 3.2 for Group 2. He also finds that the standard deviation for Group 1 was 9.2 whereas for Group 2 it was 11.6. After analysis, Dr Citizen uploaded the data and findings, then shared the access link with all participants.

1.   What is the aim of the experiment? (1)
2.   Write a suitable research hypothesis (1)
3.   Operationalise the dependent and independent variables (2)
4.   What experimental design was used? (1)
a.   List one advantage of this design (1)
5.   List two limitations of this experiment (2)
6.   Suggest two possible improvements to the experiment (2)
7.   What type of data did Dr John Citizen collect? (1)
8.   Comment any ethical concerns surrounding the experiment (2)
9.   Can Dr Citizen’s findings be generalised? Explain. (2)
10.   Which group showed greatest variation in results? (1)

1. Aim: to investigate whether blue tablets are more effective than white tablets in relieving pain.

2. Hypothesis: It is hypothesisied that healthy adults aged 18-30, that are given a dossage of Blue Paingo tablets will likely experience lower levels of  pain one hour after taking the tablet, as measured by participant's subjective rating of pain on a scale of 1-10, compared to those who have been given a dossage of White Paingo tablets.

3. IV:  The colour of the tablet; taking a dosage of blue coloured paingo tablets, or taking a dosage of white coloured paingo tablets `
DV: The degree of pain experienced as measured by a rating scale from 1-10

4.Independent groups
a.) An advantage of an indpendent groups reearch design is that it is easy to administer and is time and cost effective.

5.
- The use of a rating scale as a means of collecting data: a limitation of using this form of data collection is that the validity of the results measured is dependent on the honesty of participants, therefore participants may be dishonest, which will in turn mean that the results of the experiment would be potentially unreliable and not accuratley measuring the impact of colour on pain relief.
- Another limitation is the use of convinience sampling which means the sample is likely unrepresintitive of the wider population

6.- An improvement to the experiment could be using a different sampling technique, other than convinience sampling to obtain a more representitive sample
-Using a repeated measures research design so that individual participant related differences are accounted for.

7. Quantitive, Primary, Subjective data

8. 
-Debreiefing: Although, participants recieved the data, for a debreifing process to be adhered to properly, dberiefing should be a thorough process, whereby the researcher discusses the experiment and the results with the participants in detail, ensuring any concerns or questions they have are adrressed.
-Beneficience: In an experiment the researcher should ensure any risk to participants is minismised, and the benefits of the experiment must outweigh any potential risks, the aim of the study or any benefits do not outweigh the potential risk of a participant using the medication inappropriatly.
Volountary participation: Becuase the experimentor has a personal affiliation with the participants, there is a chance he may have potentially coerced them or made them feel pressured to take part in the experiment.

9. The findings of the experiment cannot be generalised because the sample was not representitive of the population.

10. Group 2, showed a greater variation in results with a standard deviation of 11.6

Hypothesis: It is hypothesisied that healthy adults aged 18-30, that are given a dossage of Blue Paingo tablets will likely experience lower levels of  pain one hour after taking the tablet, as measured by participant's subjective rating of pain on a scale of 1-10, compared to those who have been given a dossage of White Paingo tablets.

3. IV:  The colour of the tablet; taking a dosage of blue coloured paingo tablets, or taking a dosage of white coloured paingo tablets `
DV: The degree of pain experienced as measured by a rating scale from 1-10

4.Independent groups
a.) An advantage of an indpendent groups reearch design is that it is easy to administer and is time and cost effective.

5.
- The use of a rating scale as a means of collecting data: a limitation of using this form of data collection is that the validity of the results measures is dependent on the honesty of participants, therefore participants may be dishonest, which will in turn mean that the results of the experiment would be potentially unreliable and not accuratley measuring the impact of colour on pain relief.
- Another limitation is the use of convinience sampling which means the sample is likely unrepresintitive of the wider population

6.- An improvement to the experiment could be using a different sampling technique, other than convinience sampling to obtain a more representitive sample
-Using a repeated measures research design so that individual participant related differences are accounted for.

7. Quantitive, Primary, Subjective data

8. 
-Debreiefing: Although, participants recieved the data, for a debreifing process to be adhered to properly, dberiefing should be a thorough process, whereby the researcher discusses the experiment and the results with the participants in detail, ensuring any concerns or questions they have are adrressed.
-Beneficience: In an experiment the researcher should ensure any risk to participants is minismised, and the benefits of the experiment must outweigh any potential risks, the aim of the study or any benefits do not outweigh the potential risk of a participant using the medication inappropriatly.
Volountary participation: Becuase the experimentor has a personal affiliation with the participants, there is a chance he may have potentially coerced them or made them feel pressured to take part in the experiment.

9. The findings of the experiment cannot be generalised because the sample was not representitive of the population.

10. Group 2, showed a greater variation in results with a standard deviation of 11.6

For 6 Your first idea is definitely valid but I do think that your answer would be stronger if you included a sampling procedure that could be used in it. Using a repeated measures design introduces order effects and therefore may not reduce the impact of extraneous variables in comparison with independent groups so I'd suggest listing a stronger advantage. (There are potential ideas listed in the feedback for carolinsale-17 and saringiya)

For 8 Questioning beneficience is a weaker answer than your others as this level of medication would be very readily accessible to the participants anyway and they are very unlikely to accidentally misuse the medication. Thus it is unlikely that the experiment would significantly increase the risk of damage due to ill use of medication.

Some of your answers are quite detailed which can help you get marks but doing it unnecessarily increases the risk of running out of time so I recommend trying to cut done on this where you safely can. (eg. variables do not need to be operationalised in your hypothesis)

That being said, your answers do show good familiarity with the course content - especially for so early in the year.

2. It is hypothesized that adults who take a blue PainGo tablet will have a greater reduction in perceived pain levels one hour after taking the tablet, as compared to those who took a white PainGo tablet.
3. The independent variable is the colour of the PainGo tablet, either white or blue with the addition of a dyeing agent.
The dependant variable is the difference in perceived pain levels before and after taking the tablet, measured on a scale of 1-10 immediately before and subsequently an hour after consumption.


I think this answer by sarangiya is an optimal answer for a hypothesis and opperationalised variables

I think this is a great answer for limitations of the experiment :)

Week 1 Answer Sheet

1.   
Aim: to investigate whether blue tablets are more effective than white tablets in relieving pain.
2.   
It is hypothesized that adults who take a blue PainGo tablet will have a greater reduction in perceived pain levels one hour after taking the tablet, as compared to those who took a white PainGo tablet
3.   
3. IV - blue or white colour of the PainGo tablet.
4.   DV - recorded level of pain on a scale from 1-10 before and one hour after taking the PainGo tablet
5.   
One limitation might be the self-reporting of pain levels. Validity of the participants' responses may be questioned because of cognitive biases, exaggeration and lack of standardization. Another limitation might be the use of an independent groups design. The individual differences in participants are an extraneous variable; differing pain tolerances or attitudes towards medication between participates may affect their reporting on the effectiveness of the tablet.
6.   
Experiment can be improved by using a different sampling method such as random sampling, which is more representative of the population than convenience sampling. It can also be improved by using a greater sample size such as 50-100 people as this means the experiment increases in its ability to generalize back to the population.
7.   
Quantitative, Primary, Subjective data
8.   
It is mentioned that the results are shared with all participants via an online upload link. It is not mentioned whether participants' confidentiality was protected. If all participants are able to see results of others', especially with names or other private information, it is a violation of the participants' confidentiality and privacy.
9.   
Dr. Citizens findings cannot be truly generalized to the population. This is because convenience sampling was used, which is not representative of the wider population.
10.   Group 2
