Finding the Median in Data Sets

The video tutorial explains how to find the median of a data set. It begins by defining the median as the central value and demonstrates how to order numbers from least to greatest. The tutorial then shows how to find the median in a data set with an even number of values by calculating the average of the two middle numbers. The example used involves the numbers 13, 17, 25, and 41, resulting in a median of 21.

What is the first step in finding the median of a data set?

• Multiply the numbers

• Find the average of the numbers

• Order the numbers from least to greatest

• Add all the numbers together

How do you determine the median in a data set with an even number of values?
