What This Calculator Does
The Mean, Median & Mode Calculator finds all three measures of central tendency from a list of numbers, plus sum, count, and range.
How It Works
Mean is the sum divided by count. Median is the middle value when sorted (or average of the two middle values for even counts). Mode is the most frequent value; bimodal and multimodal datasets are detected.
Example
For 3, 7, 7, 2, 9: mean = 5.6, median = 7, mode = 7, range = 7.
Formula
Mean = Sum / CountMiddle value of sorted datasetReading the Results
Mean
The arithmetic average of all values.
Median
The middle value that separates the lower and upper halves.
Mode
The value(s) that appear most frequently.
Frequently Asked Questions
What if there are multiple modes?
The calculator shows all values that share the highest frequency. A dataset with two modes is bimodal; three or more is multimodal.
Which measure should I use?
Mean is best for symmetric data without outliers. Median is better for skewed data. Mode is useful for categorical or discrete data.
Can I enter negative numbers?
Yes. Negative numbers, decimals, and mixed formats all work.
