Lesson Plan: Grouped Frequency Tables: Estimating the Mean Mathematics • Second Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to estimate the mean using grouped frequency tables.
Objectives
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.
Prerequisites
Students should already be familiar with
- grouped frequency tables.
Exclusions
Students will not cover
- calculating an estimate for the median of grouped data,
- calculating an estimate for the mode of grouped data.
