Mean, Median & Mode Calculator

Q: What is the mean of 2, 4, 6, 8, 10?

The mean is 6. Add all values: 2 + 4 + 6 + 8 + 10 = 30. Divide by the count: 30 / 5 = 6.

Q: How do you find the median of an even-numbered data set?

Sort the values in order, then average the two middle values. For example, the median of {2, 4, 6, 8} is (4 + 6) / 2 = 5.

Q: Can a data set have more than one mode?

Yes. A data set with two modes is called bimodal, and one with more than two modes is multimodal. If no value repeats, the data set has no mode.

Sorted data & working

Mean vs Median vs Mode

Mean (average): sum all values, divide by count. Median: the middle value when sorted — if even count, average the two middle values. Mode: the value that appears most often — a dataset can have multiple modes or none.

Standard Deviation

Standard deviation measures how spread out the values are from the mean. A low standard deviation means values are clustered near the mean; a high standard deviation means they are spread out widely.

Frequently Asked Questions

What is the mean of 2, 4, 6, 8, 10?

The mean is 6. Sum = 2+4+6+8+10 = 30. Divide by count: 30 ÷ 5 = 6.

How do you find the median of an even-numbered data set?

Sort the values, then average the two middle values. For {2, 4, 6, 8}: median = (4 + 6) ÷ 2 = 5.

Can a data set have more than one mode?

Yes. Two modes = bimodal; more than two = multimodal. If no value repeats, the data set has no mode.
