Mrs. Potter’s class was more consistent because their standard deviation of 3 points was lower.

What is a statistical dispersion?

A statistical dispersion is also referred to as degree of dispersion and it can be defined as a measure of the extent to which a numerical value (data) is likely to vary about a mean or an average value.

In Mathematics, there are four measures of dispersion for a data set and these include the following:

  • Range
  • Interquartile range
  • Variance
  • Standard deviation

In this scenario, we can infer and logically conclude that Mrs. Potter’s class was more consistent than Mr. Jones class because their standard deviation of 3 points was lower.
