If we are going to predict future performance on the basis of a sample mean and sample standard deviation,it is desirable to have a
A)small mean.
B)small standard deviation.
C)large mean.
D)large standard deviation.

Question

Quizplus · Accepted Answer

A small standard deviation indicates that the data is tightly clustered around the mean, providing a more accurate estimate of future performance. A large standard deviation would indicate that there is a lot of variability in the data, making it difficult to predict future performance with accuracy. A small or large mean does not have a significant impact on the ability to predict future performance based on sample statistics.
