What is mean Average using middle points or center class?

The mean average using midpoints or center class involves calculating the mean of grouped data by first determining the midpoint of each class interval. The midpoint is found by averaging the upper and lower boundaries of the class. Then, you multiply each midpoint by the frequency of its corresponding class, sum these products, and divide the total by the overall frequency to obtain the mean. This method is particularly useful for summarizing data that is organized into classes or intervals.
