    How to find each one

    Mean

    Add every value, then divide by the number of values. For 2, 4, 9: (2 + 4 + 9) ÷ 3 = 5.

    Median

    Sort the values from smallest to largest and pick the middle one. With an even count, average the two middle values.

    Mode

    Count how many times each value appears. The value with the highest count is the mode. There can be one, several or none.

    Range

    Subtract the smallest value from the largest.

    A quick memory trick

    Mean is the "mean" one because you have to do the most work. Median sounds like the median strip in the middle of a road. Mode sounds like "most". Range is the distance from lowest to highest.

    Why the three can disagree

    Imagine five salaries: $40k, $42k, $45k, $47k and $300k. The mean is $94.8k, but four of the five people earn less than $50k. The median, $45k, is a far better picture of a typical salary. This is why news reports usually quote median income and median home prices.

    Frequently asked questions

    What is the difference between mean, median and mode?

    The mean is the average: add all the values and divide by how many there are. The median is the middle value when the numbers are sorted. The mode is the value that appears most often. Together they describe the "center" of a data set in three different ways.

    How do you find the median with an even number of values?

    Sort the numbers and take the two in the middle, then average them. For 3, 5, 8, 10 the middle two are 5 and 8, so the median is 6.5.

    Can there be more than one mode?

    Yes. If two values tie for most frequent, the data is bimodal and has two modes. If several values tie, it is multimodal. If every value appears only once, there is no mode.

    Which is better, mean or median?

    The median is better when the data has outliers or is skewed, such as house prices or incomes, because a few very large values pull the mean up. The mean is better for symmetric data without extreme values because it uses every number.

    What is the range?

    The range is the largest value minus the smallest. It is a quick measure of how spread out the data is, although a single outlier can make it large.
