Question

A random sample of 10 subjects have weights with a standard deviation of 11.9458 kg. what is the variance of their weights? be sure to include the ap

Answer 1

The variance of their weights is 142.70213764Kg^2

Given:

s = 11.9458 kg

The variance is the square of the standard deviation:

s^2 = 11.9458 ^2 = 142.70213764

The units of the variance are the units of the standard deviation squared, thus in this case kg^22.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
