Which measure of dispersion indicates the extent to which each individual score in a data set varies from the mean of that set?

range

standard deviation

median

mean

Option 2 - Standard deviation

Explanation:

To find : Which measure of dispersion indicates the extent to which each individual score in a data set varies from the mean of that set?

Solution :

Standard deviation is defined as,

It is a mathematical measure that is used to evaluate the difference between the mean value of a set of number and each value in the group.It is calculated as the square root of variance by determining the variation between each data point relative to the mean.

The measure of dispersion that indicates how much scores in a sample vary around the mean of the sample is the standard deviation.

Therefore, option 2 is correct.
