What makes the mean less useful in predicting highly variable data sets?

• The mean is not accurate

• The mean is not representative

• The measurement error is higher

• The mean is inconsistent

What does variability indicate about the data?

• How consistent the scores are

• How much the scores differ from each other

• The mean of the data set

• The mode of the data set
