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.
How do you calculate an estimate of mean length using midpoints of class intervals?
To estimate the mean length using midpoints of class intervals, first determine the midpoint for each class interval by averaging the lower and upper bounds of the interval. Then, multiply each midpoint by the frequency of its corresponding class to find the total for that class. Finally, sum all these products and divide by the total number of observations (the sum of all frequencies) to obtain the estimated mean. The formula can be summarized as: ( \text{Mean} = \frac{\sum ( \text{midpoint} \times \text{frequency})}{\sum \text{frequency}} ).

Do you divide your mean by 4 or 2?
You divide by the number of numbers - if you want the mean of three numbers you divide by 3, if you want the mean of a hundred numbers you divide by 100.
