Lesson 3: Proportions

In this lesson, we’ll look at the basics of using proportions and percentages to summarize different aspects of data with two or more variables. We’ll also add another powerful Excel tool to our toolbelts: crosstabs/pivot tables.

Lab: Proportions

Hopefully you’re not getting tired of coffee talk yet, because in this lab, we’ll create a crosstab for two of the categorical variables in the coffee data set we’ve been using. Using pivot tables, we’ll organize these categories into raw counts and proportions in a couple different ways.

The lab instructions can be downloaded as a PDF file here.

The data set for this lab can be viewed here. From the link, copy and paste all the data into a new worksheet in Excel Online.

(Note: This lab uses the same data set you used in the labs for the previous module.)
