Mean, Median, and Mode Calculator

Enter your data values and instantly calculate all three measures of central tendency with step-by-step solutions.

  • Mean — the arithmetic average (sum ÷ count)
  • Median — the middle value when data is sorted
  • Mode — the most frequently occurring value

Formulas Used

Mean (arithmetic average)

Median (odd n)

Median (even n)

Mode

How to Use This Calculator

  1. Enter your data as comma-separated numbers (e.g., 4, 8, 6, 5, 7, 8, 3)
  2. See all three results instantly with full step-by-step breakdowns
  3. Compare — see which measure best represents your data

Every calculation shows the exact steps so you can learn the method while getting your answer.

When to Use Each Measure

  • Mean — best for symmetric data without outliers (test scores, measurements)
  • Median — best when data is skewed or has outliers (salaries, home prices)
  • Mode — best for categorical data or finding the most common value (shoe sizes, survey responses)
