Lesson: Grouped Frequency Tables: Estimating the Mean Mathematics • Second Year of Preparatory School

Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to estimate the mean using grouped frequency tables.

Students will be able to

recognize that, for grouped data, you can only calculate an estimate for the mean if you do not know the source data,
calculate the midpoints of classes in a grouped frequency table,
form an extended frequency table to help calculate an estimate for the mean,
calculate an estimate for the mean of grouped data.
