How do you find mid point when class interval and ffrequency is given?
To find the midpoint of a class interval, you add the lower limit and the upper limit of the interval and then divide the sum by 2. For example, if the class interval is 10-20, the midpoint would be (10 + 20) / 2 = 15. This midpoint can then be used in calculations like finding the mean or in statistical analysis involving frequency distributions.
How do you find the midpoint in grouped frequency tables?
To find the midpoint in grouped frequency tables, first identify the class intervals. The midpoint for each class interval is calculated by averaging the lower and upper boundaries of the interval, using the formula: ( \text{Midpoint} = \frac{\text{Lower limit} + \text{Upper limit}}{2} ). Once you have the midpoints for all intervals, you can use them for further statistical calculations, such as estimating the mean.
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.

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)).

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.
