Question

In what type of data would you use the mean as a balance point to describe the data? Select the correct option below.

Option #1: bell-shaped symmetrical data

Option #2: right-leaning data

Option #3: left-leaning data

Option #4: U-shaped data

Answer 1

Option #1: bell-shaped symmetrical data.

Explanation: The mean is a good "balance point" measure when the distribution is symmetric (e.g., approximately normal). In skewed (right-leaning or left-leaning) or U-shaped distributions the mean is pulled by extremes and not a reliable center—use the median (or other measures) instead.
