Explanation

Mean: sum of all values divided by count. Affected by outliers. Median: middle value when ordered (or average of two middle values). Not affected by outliers.

Mode: most frequent value. Can have multiple modes or no mode. Best for categorical data. Range: highest minus lowest – measures spread.

Choose based on data: mean for symmetric distributions, median for skewed data or when outliers exist, mode for categorical data or finding most common value.
