Lesson Plan: Standard Deviation of a Data Set Mathematics • 9th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find and interpret the standard deviation from a given data set.
Objectives
Students will be able to
- understand what a measure of dispersion means and recall the formula for the standard deviation,
- calculate the standard deviation from a list of data,
- calculate the standard deviation from a frequency table,
- calculate the standard deviation from a grouped frequency table,
- use the measure of dispersion to make judgements about data.
Prerequisites
Students should already be familiar with
- the mean and range of a data set,
- methods for collecting and displaying data such as frequency tables,
- summation notation.
Exclusions
Students will not cover
- variance of a data set,
- the standard deviation or variance of discrete or continuous random variables,
- calculating sample variance or sample standard deviation.
