It is the midpoint of a given class interval.
Question
It is the midpoint of a given class interval.
Solution
The midpoint of a given class interval can be found using the following steps:
-
Identify the lower and upper limits of the class interval. For example, if the class interval is 10-20, the lower limit is 10 and the upper limit is 20.
-
Add the lower limit and the upper limit together. In our example, this would be 10 + 20 = 30.
-
Divide the sum by 2 to find the midpoint. In our example, 30 ÷ 2 = 15. So, the midpoint of the class interval 10-20 is 15.
