The mean of sample x is 5.83
The standard deviation is 5.63
<h3>What is standard deviation?</h3>
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.
Given:
Frequency: 2 2 4 13 13 1
If x is the pair of sneakers owned of the frequency,
mean = 2+2+4+13+13+1/5
= 35/6
= 5.83
The standard deviation is equal to 5.63.
