Mean Median Mode Calculator

Calculate the three most common measures of central tendency.

Methodology, assumptions, and limitations

The mean divides the sum by the count, the median uses the middle ordered value or average of the two middle values, and the mode identifies the most frequent value. Showing all three reveals when skew or repeated observations affect the center.

Assumptions
  • Entries belong to one comparable numerical dataset.
  • Repeated values are intentional observations.
  • Missing values are excluded rather than treated as zero.
Limitations
  • The mean is sensitive to extreme values.
  • A dataset can have no mode or several modes.
  • Measures of center do not describe variability by themselves.

How to Use

Step-by-step instructions
  1. 1Enter your dataset separated by commas or spaces.
  2. 2The calculator will compute the mean, median, and mode.

Central Tendency

The mean is the arithmetic average. The median is the middle value when sorted. The mode is the value that appears most frequently.
Mean = Sx/n, Median = Middle Value, Mode = Most Frequent

Variables:

xData values
nSample size

Example

Dataset: 1, 2, 2, 3, 4

Inputs:

Data:1, 2, 2, 3, 4

Steps:

  1. 1.Mean: (1+2+2+3+4)/5 = 2.4
  2. 2.Median: 2 (middle value)
  3. 3.Mode: 2 (appears twice)
Result:
Mean: 2.4, Median: 2, Mode: 2

Frequently Asked Questions

Can there be more than one mode?

Yes, if multiple values share the highest frequency, the dataset is multimodal.
