mean median mode

Explanation:

(a) The mode is defined as the most frequently occurring value in a dataset, so it identifies the most common number of children.
(b) The salary data has no extreme outliers and is relatively evenly distributed; the mean is a good summary for such symmetric, non-skewed data.
(c) The calorie data is a set of values with no repeated entries (no mode) and is roughly symmetric, so the mean is an appropriate summary measure.
