Geoffrey is looking at two datasets, each of which has the same mean. How can he determine which of the two datasets has less variability?(1 point)

Question

Responses

The datasets have the same variability because their means are the same.
The datasets have the same variability because their means are the same.

The dataset with less variability has a greater deviation.
The dataset with less variability has a greater deviation.

The dataset with more pieces of data will have less variability.
The dataset with more pieces of data will have less variability.

The dataset with less variability has a smaller deviation.

Answer 1

To determine which of the two datasets has less variability, Geoffrey should look at the measure of dispersion, such as the standard deviation or variance, rather than the mean. The correct response is:

The dataset with less variability has a smaller deviation.
