# Simple Box Plot question

Hi all,

I have a simple question that I need your help with. I have a box plot which shows the medians, 1st and 3rd quartiles, and min/max values. I was wondering if I can get the mean and standard deviation using this information

Thanks..

Traditional box plot does not contain the mean and standard deviation.
They usually include the five number summary as you suggested, and
possibly mark some outliers.

Of course some people will indicate the mean in the box plot too, but in
general you cannot precisely calculate the mean/standard deviation.

Unless you have some (parametric) model assumption, otherwise you can
only have some rough idea about the mean/SD of the distribution based
purely on the five number summary.
