Why is class midpoint in statistical formulas important?
When data are summarised into classes, their exact values are lost. There is no way of knowing whether the original observations were near the bottom of the class, the top of the class or evenly spread out. Assuming that all the observations that fall into a particular class take the midpoint value is a reasonable approximation. It is the maximum likelihood unbiased estimate. It also sets the variance within each class to 0.

What does the midpoint formula give you the midpoint of?

How do you find class midpoint?
It is the middle of the class. e.g. 0<l<10 - class midpoint is 5 because it is the middle of the class. e.g. 25<t<50 - class midpoint is 37.5 because it is the middle of the class Midpoint = MIDDLE

Class midpoint in statistics?
It is the midpoint of the class interval. I.e let b=the highest number in the class, a = the lowest number in the class. The midpoint is (a+ 1/2(b-a)).
What is the class midpoint?

What is the midpoint of the class 16-19?

What is a 'crude mode'?
Crude Mode (Grouped data) is the midpoint of the class limit with the highest frequency. Therefore, in getting the Crude Mode, look for the highest frequency and look at it's class limit. Lastly, get he class limit's midpoint. The Class Limit's midpoint will be the Crude Mode (Grouped Data).
What is the class midpoint of scores interval 95-99?
97
Does the midpoint of a frequency distribution class equal the sum of the lower and upper limits?
No, the midpoint is the result of adding the upper and lower limits in a class and dividing that by 2. Essentially the mid point is the average of the two limits.

The class midpoint
