## Graphing

Read these sections and complete the questions at the end of each section. First, we'll look at the available methods to portray distributions of quantitative variables. Then, we'll introduce the stem and leaf plot and how to capture the frequency of your data. We'll also discuss box plots for the purpose of identifying outliers and for comparing distributions and bar charts for quantitative variables. Finally, we'll talk about line graphs, which are based on bar graphs.

### Frequency Polygons

#### Questions

**Question 1 out of 3.**

A frequency polygon is very similar to a

- histogram
- stem and leaf display
- listing of raw data

**Question 2 out of 3.**

Check all that apply. Frequency polygons are better than histograms for:

- showing the shape of the distribution
- comparing distributions
- revealing the exact values in a distribution

**Question 3 out of 3.**

Response times were generally shorter to the

- large target
- small target
