The median is a statistical measure that represents the middle value in a dataset when the data is ordered from least to greatest. Here's a breakdown:
How to find the median:
1. Order the data: Arrange the numbers in your dataset from smallest to largest.
2. Find the middle value:
* Odd number of data points: The median is the middle value.
* Even number of data points: The median is the average of the two middle values.
Example:
Let's say we have the following dataset: 2, 5, 8, 10, 12
1. The data is already ordered.
2. There are 5 data points (odd number), so the median is the middle value, which is 8.
Why is the median important?
* Resistant to outliers: The median is less affected by extreme values (outliers) than the average (mean).
* Provides a sense of central tendency: It gives you a good idea of the "typical" value in a dataset.
In contrast to the mean:
* The mean is the average of all values in a dataset. It can be heavily influenced by outliers.
