The Mean Median Mode Calculator is an advanced online utility that helps you quickly determine measures of central tendency and spread — mean, median, mode and range. It works for both discrete and continuous datasets, making it an essential tool for students, teachers, researchers and professionals in data-driven fields.

The mean is the arithmetic average of a dataset. Add all values together and divide by the total number of observations.

Formula: x̄ = ΣXi / n

Example: Dataset = 7,6,9,4,5,6,8 → Mean = 45 ÷ 7 = 6.42

You can also compute Geometric Mean (nth root of product of all values) and Harmonic Mean (reciprocal of average of reciprocals) with our calculator.

The median is the middle value of an ordered dataset. If the dataset has an odd number of values, the median is the central value. If even, it’s the average of the two middle values.

Example: Dataset = 1,2,3,4,6,7,9 → Median = 4

The median is especially useful in skewed distributions, where the mean may be misleading.

The mode is the value that appears most frequently in a dataset. A dataset can have:

• One mode: Unimodal
• Two modes: Bimodal
• More than two modes: Multimodal
• No mode: If all values appear equally

Example: Dataset = 8,4,9,1,4,2,4,1 → Mode = 4

The range measures the spread of a dataset by subtracting the smallest value from the largest.

Formula: Range = Max – Min

Example: Dataset = 6,8,9,10,14 → Range = 14 – 6 = 8

1. Enter your dataset into the input box (comma-separated).

• Easy-to-Use: Simple interface for students and professionals alike.

1. Ensure Accuracy: Enter numbers correctly to avoid errors.
2. Clean Data: Remove outliers if they distort results.
3. Pick the Right Measure: Use mean for balanced data, median for skewed data and mode for categorical/frequency-based data.
4. Use Range with Care: Range can be misleading if extreme values are present.
5. Combine Measures: For better insights, analyze mean, median and mode together.
