Calculate the mean and standard deviation of returns for each of the above series. Also compute the minimum, maximum and 1st, 2nd and 3rd quartile of returns for each series. Also produce a boxplot for these series. Comment critically on your results."

Hi, I have finished all the questions related to the data above.

I just don't understand how to comment critically.

Basically, we have 10 datasets from 10 different bonds based on 10 years of time. I have got the answer for 10 years mean, sd, boxplot, MIN,Q1 Q2 Q 3, and MAX. But how to make the comment, like from which aspect? Compare with each other or compare with itself but according to different times?

I do understand the formula and process to solve sd, mean

So no need to explain the formulas or functions.
