Question 1

What is a measure of central tendency?

Accepted Answer

A statistic that describes the center or typical value of a dataset, commonly the mean, median, or mode.

Question 2

What is the mode of a dataset?

Accepted Answer

The value(s) that occur most frequently; a dataset can be unimodal, multimodal, or have no mode.

Question 3

How do outliers affect the mean and median, and when should you use each measure (mean, median, mode)?

Accepted Answer

Outliers pull the mean toward them, while the median is resistant. Use mean for roughly symmetric data without extreme outliers; median for skewed data or with outliers; mode for categorical data or when the most common value is desired.
