Question

what value for the standard deviation on a distribution of exam scores would make any score relative to the others be considered more extreme?
○ 2
○ 8
○ not enough information
○ 4

Explanation:

Step1: Understand standard - deviation concept

Standard deviation measures the spread of data. A smaller standard deviation means data points are closer to the mean, and a larger one means they are more spread out. A smaller standard deviation makes a given score more extreme relative to others because scores are clustered more tightly around the mean.

Step2: Compare given values

Among 2, 4, 8, the smallest value is 2.

Answer:

A. 2
