# How to Calculate Mean, Median and Mode in SPSS

In statistics, there are three common ways to measure where the “center” of a dataset is located:

• Mean: The average value.
• Median: The middle value, located at the 50th percentile.
• Mode: The most commonly occurring value.

These are known as measures of central tendency.

The easiest way to calculate the mean, median and mode in SPSS is to use Analyze > Descriptive Statistics > Frequencies.

The following example shows how to do so in practice.

## Example: How to Calculate Mean, Median and Mode in SPSS

Suppose we have the following dataset in SPSS that shows the exam scores received by various students in some class:

Suppose that we would like to calculate the mean, median and mode of the exam scores.

To do so, click the Analyze tab, then click Descriptive Statistics, then click Frequencies:

In the new window that appears, drag Exam_Score to the Variables panel:

Then click the Statistics button.

In the new window that appears, check the boxes next to Mean, Median and Mode under the Central Tendency group:

Then click Continue. Then click OK.

The following output will appear:

The first table in the output titled Statistics contains the values of the mean, median and mode of exam scores.

From this table we can see:

• Mean exam score: 89.67
• Median exam score: 92
• Mode exam score: 97

The second table then shows the frequency of each unique exam score.

From this table we can see that the value 97 occurs 3 times, which is the most frequently occurring value and thus the mode.
