R-script file under the sub-heading Module 2, and the statistical outputs under the
sub-heading “Module 2” in the Word file. In general, your statistical outputs
should be titled and labeled so that they can stand on their own (and can be
understood by anyone who looks at them for the first time).
1. Produce several descriptive statistics tables (i.e. mean, SD, min, max, and
N) for the entire sample, and by group (for example, by the class=1 to 3).
You may use commands of your choice. What is a three-line table format
that is commonly used in white papers? Provide several interpretive
sentences with your table outputs.
2. Use img( ) and par( ), and abline( ) with various plot making commands to
produce scatter chart, jitter chart, and boxplot chart. When do you use jitter
chart? How can you use boxplots to detect outliers? Export the charts to the
Word document and provide several interpretative sentences of your
findings.
Submit a report that examines parts 1 and 2 and your R script.
