Question
The middle number of a list of data when the numbers are arranged in order from the least to greatest
- mean
- range
- mode
- median
Solution
The middle number of a list of data when the numbers are arranged in order from the least to greatest is called the median. Here are the steps to find it:
-
Arrange the numbers in order from least to greatest. If you have a list like this: 5, 1, 9, 3, 7 - you would rearrange it to look like this: 1, 3, 5, 7, 9.
-
Determine if the number of data points is odd or even. In our example, we have 5 data points, which is an odd number.
-
If the number of data points is odd, the median is the number that is in the middle of the list. In our example, the median would be 5 because it is the middle number.
-
If the number of data points is even, the median is the average of the two middle numbers. For example, if our list was 1, 3, 5, 7 - the median would be 4, because (3+5)/2 = 4.
