To determine which dataset has the least variability, we look at the standard deviations of each dataset. The smaller the standard deviation, the less variability it has.

Here are the standard deviations for each dataset:

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

Among these, Dataset 3 has the smallest standard deviation of 1.19, which indicates it has the least variability.

Answer: Dataset 3
