To determine which dataset has the highest variability, we can look at the standard deviation. The standard deviation indicates how much the data points vary from the mean: a higher standard deviation corresponds to higher variability.

Here are the standard deviations for the datasets:

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

Among these, Dataset 2 has the highest standard deviation of 1.42.

Therefore, Dataset 2 has the highest variability.
