Median

In statistics, the median is a measure of central tendency that represents the middle value of a data set when it is ordered from least to greatest. It is the value that separates the higher half from the lower half of the data set. To find the median, you need to arrange the data in ascending order and then determine the middle value.

Finding the Median

To find the median of a set of data:

1. Arrange the data in ascending order.
2. If the number of data points is odd, the median is the middle value.
3. If the number of data points is even, the median is the average of the two middle values.

Example

Consider the following data set: 12, 5, 8, 9, 10, 14, 7

Arranging the data in ascending order: 5, 7, 8, 9, 10, 12, 14

Since the number of data points is odd (7), the median is the middle value, which is 9.

Study Guide

To find the median of a set of data:

1. Arrange the data in ascending order.
2. If the number of data points is odd, the median is the middle value.
3. If the number of data points is even, the median is the average of the two middle values.

Remember to practice finding the median of different data sets to strengthen your understanding of this concept.

Understanding the median is crucial in statistics and is often used to describe the center of a data set. It is important to be able to calculate the median accurately and efficiently.
