Data Sessoin 4:  The Five-Number Summary
 

Sessions 2 and 3 explored different ways to organize data in order to draw out patterns in the variation. In these sessions, we investigated a variety of approaches to organizing data in graphs and tables and examined some of the different ways we can answer statistical questions, based on these representations.

In this session, we will explore how dividing data into groups can give us yet another way to answer statistical questions. Note 1

In This Session:

Part A:

Min, Max, and the Two-Number Summary

Part B:

The Median and the Three-Number Summary

Part C:

Quartiles and the Five-Number Summary

Part D:

The Box Plot

Part E:

Finding the Five-Number Summary Numerically

Learning Objectives

The goal of this session is to learn how dividing data into groups can help us provide other types of answers to statistical questions. In this session, you will learn how to do the following:

• 

Understand the median as the value that divides the ordered data into two groups, with the same number of data values (approximately one-half) in each group

• 

Understand quartiles as the values that divide the ordered data into four groups, with the same number of data values (approximately one-fourth) in each group

• 

Investigate the concept of quartiles using several different representations

• 

Summarize an entire data set with a Five-Number Summary

• 

Summarize an entire data set with a box plot
