Summary: This chapter will introduce the basic tools for analyzing data for categorical
and quantitative variables. Data analysis is the process of describing data using graphs and
numerical summaries. Categorical variables are displayed with bar graphs and sometimes
pie charts. The use of counts and percents help summarize the data. Quantitative
variables are analyzed by using the following flow chart.
