# Variance and Standard Deviation of Weights

Collect data consisting of at least 20 values. (You may also create a data set with reasonable values for your variable).

The values are given represent the weights of the 20 kids in the first grade class room:

36, 36, 37, 37, 38, 38, 41, 41, 41, 42, 42, 42, 42, 43, 44, 44, 44, 45, 45, 45,

a.Define the variable - the weight in pounds - it is a dependent variable.

b.Find the mean, median, mode, variance, and standard deviation for your data.

Mean - 41.15

Mode - 42

Variance =

Please help me figure out the variance and standard deviation to this scenario.
