How do I calculate the mean?

Add all the numbers together and divide by the count. For example, the mean of 2, 4, 6 is (2+4+6)/3 = 4.

The median is the middle value when numbers are sorted. For an even count, it's the average of the two middle values.

The mode is the value that appears most frequently in a data set. A set can have one mode, multiple modes, or no mode at all.

What is an Average?

An average (arithmetic mean) is the sum of all values divided by the number of values. It is the most common measure of central tendency and is used in statistics, academics, finance, and everyday life to represent a typical value in a data set.

Statistical Measures

1. Mean (Arithmetic Average)

Mean = Sum of values ÷ Count of values

2. Median

Middle value when sorted. For even count: average of two middle values.

3. Mode

Most frequently occurring value(s).

4. Range

Range = Maximum value − Minimum value

Examples

Mean of 2, 4, 6: (2+4+6) ÷ 3 = 4
Median of 3, 1, 4, 1, 5: Sorted: 1, 1, 3, 4, 5 → Middle = 3
Mode of 1, 2, 2, 3, 4: 2 (appears most often)
Range of 10, 20, 30: 30 − 10 = 20

When to Use Each Measure

Mean: Best for symmetrical distributions without outliers (e.g., test scores).
Median: Best when data has outliers or is skewed (e.g., income data).
Mode: Best for categorical data or finding the most common value (e.g., shoe sizes).
Range: Quick measure of data spread; sensitive to outliers.
