Describe each data set. That is, determine the shape, center and spread. Which mutual fund would you invest in and why? Also calculate the CV for both sets of data."

I know the formula for the CV is (s/x̄)x100%, and i found x̄ to be 3.05 for A, and 3.41 for B. But i do not know how to get the s value. Also, i do not know what "center and spread" mean. Could someone help me please?

p.s. x̄ is "x-bar"
