About Mean, Median, Mode Calculator

Mean, median, and mode are the three fundamental measures of central tendency in statistics used to describe the center point of a distribution.

What is Mean, Median, Mode Calculator?

Mean, median, and mode are the three fundamental measures of central tendency in statistics used to describe the center point of a distribution.

How to Use This Calculator

  1. Enter raw data points separated by commas or spaces.
  2. The tool automatically sorts the values in ascending order.
  3. Review mean, median, mode, range, and total count.

The Mathematical Formula & Variables

Mean = Sum of values / Count of values; Median = Middle value of sorted set; Mode = Most frequently occurring value

Variables Definition

Symbol / Variable Name Description
n Sample Size Total count of data observations.

Step-by-Step Worked Example

Scenario: Numbers: 12, 15, 18, 20, 21, 25.

  1. Sum = 12 + 15 + 18 + 20 + 21 + 25 = 111.
  2. Mean = 111 / 6 = 18.5.
  3. Middle values are 18 and 20. Median = (18 + 20) / 2 = 19.

Result: Mean = 18.5 | Median = 19

Frequently Asked Questions

When is the median preferred over the mean?

The median is preferred when a dataset contains extreme outliers or is heavily skewed (such as household income or real estate prices), because outliers distort the arithmetic mean.
