Hi..thank you for loggin on our blog... (you will never regret) Basically, this blog will focus on mode and mean of grouped data. After you have discovered this blog, we hope that you can determine the modal class from the frequency table of group data, be able to calculate the midpoint of a class, be able to verify the formula for the mean of grouped data, and be able to calculate the mean from the frequency table of grouped data. All the best to you!!!
