Mean - the sum of all values divided by the number of values.

Median - the middle number in a sorted data set.

Mode - the value that occurs most frequently.

Measures of Central Tendency- tools to find the “center” of a data set.

Mean: 10, 15, 20 → Mean = 15

Median: 3, 7, 9 → Median = 7

Mode: 4, 4, 5, 6 → Mode = 4

Mean = Average

Median = Middle

Mode = Most

Easy rhyme: Mean is the average, Median is the middle, Mode is most seen!

• A data set can have no mode at all.

Mean is very sensitive to outliers.

• Median gives a better “typical” value when data has extremes.

• In a perfectly balanced set, mean = median = mode.
