# 2.3 - Lesson 2 Summary

## Objectives

Upon successful completion of this lesson, you will be able to:

• Compute and interpret a basic proportion/risk/probability and odds
• Select and interpret the appropriate visual representations for one categorical variable, two categorical variable, and one quantitative variable
• Use Minitab Express to construct frequency tables, pie charts, bar charts, two-way tables, clustered bar charts, histograms, and dotplots
• Compute and interpret complements, intersections, unions, and conditional probabilities given a two-way table
• Identify outliers on a histogram or dotplot
• Interpret the shape of a distribution
• Compute and interpret the mean, median, mode, and standard deviation
• Compute and interpret percentiles and z scores
• Apply the Empirical Rule
• Interpret a five number summary

In this lesson, you learned how to display and summarize data concerning one categorical variable, two categorical variables, and one quantitative variable. Review the learning objectives above. You should be able to successfully complete each of these tasks before moving on. If you have any questions, post them on the Lesson 2 Discussion Board in Canvas.

In Lesson 3 we will build on this as we examine how to display and summarize data concerning the relationship between a categorical and a quantitative variable and two quantitative variables.
