1 answer

To determine which dataset has the least variability, we can use the standard deviation values. The dataset with the lowest standard deviation indicates less variability.

Here are the standard deviations for each dataset:

  • Dataset 1: Standard Deviation = 1.23
  • Dataset 2: Standard Deviation = 1.42
  • Dataset 3: Standard Deviation = 1.19

Comparing these values:

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

Dataset 3 has the lowest standard deviation (1.19), which means it has the least variability.

So, the answer is:

Dataset 3 has the lowest variability.
