1 answer

To determine which dataset has the least variability, we can compare the standard deviations of the datasets provided.

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

The dataset with the lowest standard deviation indicates the least variability.

Among the given datasets, Dataset 3 has the lowest standard deviation of 1.19.

Therefore, the answer is:

Dataset 3 has the lowest variability.
