To determine which dataset has the highest variability, you should look at the standard deviation values. Higher standard deviation indicates greater variability in the dataset.

  1. Which has the highest variability?

    • The correct response is: Dataset 2 (with a standard deviation of 1.42, which is the highest among the three datasets).

  2. How can one determine which dataset has the highest variability?

    • The correct response is: The higher variability, the higher deviation.

This means that the dataset with the highest standard deviation has the highest variability.
