Would someone mind checking me and pointing out which may be incorrect. I THINK I get it but....

Calculate the range, variance, standard deviation for the data set given 72, 80, 80, 82, 88, 90, 96?

I just wanted to know if I am doing this correctly. These are my answers. I know in my class I have to show the work and I do have it, but figured it was unnecessary for this post unless I was wrong. :)

Range= 24

Variance=53.71

Standard Deviation=7.39

Interquartile Range=10
