For our dataset, 22, 22, 25, 40, 42, 45, 46, 53, 54, 57, 63, the standard deviation is 14.3, what does the standard deviation tell us?
ANSWER:
The standard deviation measures the spread by reporting a typical (average) distance between the data points and their average.
Correct! The idea behind the standard deviation is to quantify the spread of a distribution by measuring how far the observations are from their mean. The standard deviation gives the average (or typical distance) between a data point and the mean. Great job! This is super important so it's great that you are getting this concept!
