1 answer

To determine which dataset has the least variability, we can look at the standard deviations of each dataset. The dataset with the smallest standard deviation indicates less variability.

Here are the standard deviations provided:

  • Dataset 1: 1.23
  • Dataset 2: 1.42
  • Dataset 3: 1.19

Among these, Dataset 3 has the lowest standard deviation (1.19), indicating that it has the least variability.

Thus, the completion is:

Dataset 3 has the lowest variability.
