Follow the textbook when doing the questions, but for your sac, do as you teacher says. In the exam, you wouldn't need to round, they're usually whole numbers

When you make a prediction from time-series data is it best to use the smoothed data or the original data? why why not??

Smoothed data is best, provided that there is a consistent trend (ie always increasing, or always decreasing). Smoothing removes the effects of outliers / random noise.

Hi Guys,

How would you comment on the blue (original data) and black (3 median smoothing) lines. I'm particularly not sure about the trends as they're borderline, also could you include random fluctuations in the comment?

Id say the blue is seasonal with a slighting increasing trend and the black reveals that there is no seasonality and with the trend perhaps being slightly increasing (or relatively constant not too sure!).

Much appreciated

I would definitely agree with you. However, I would also say that the blue has some irregular fluctuations (almost all data has) and the blue is slightly increasing!

Hello!
I was wondering if someone could explain 5d to me? I got $993.41 but the answer was $319.41. Thanks!

In part d, they're asking for the depreciation IN the third year, meaning by how much did it reduce by in the third year (not throughout the three years)

Thankyou that makes so much sense!

Hey Guys,

What type of distribution do you think the attached boxplot is?

Much appreciated

Positively skewed. You should keep a diagram of each in your bound reference. Google 'Boxplot distributions' for diagrams

You wouldnt think it could be approximately symmetric?

You wouldnt think it could be approximately symmetric?

From the zoom of the picture, it seems positive but idk

Hi, I was wondering what the best software is to type up your bound reference. Need help please!!!!!

Word was my saviour for Further last year .
Further is quite a wordy maths subject and I found that using Word with multiple tables seems to work well for me as it made it super easy to find something if I were to panic. You can insert equations into word or write using LaTeX too if that's your type of thing. (I currently have my Methods Bound reference on Word too and it's super handy as maths equations are easy to write into it. Plus you can convert it to a PDF when you are done for printing)

Some pictures of my old B.R are in the spoiler below if you want any ideas of how to go about constructing your own:

Hope that helps!
