  2. Get descriptive statistics for for continuous and discrete variables.

  3. Recognize what types of descriptives are appropriate for each type of variable.

  4. Recognize what types of graphs are appropriate for each type of variable.

  5. Create bar charts to display data.

  6. Create scatterplots to display relationships between variables.

10-B: Installing and Loading Packages

Note that when working through the .Rmd files, R packages will often need to be installed, and libraries loaded. Do NOT quit R while installing or loading packages and libraries. This can corrupt crucial files. Instead, you can STOP the process (by clicking the red stop sign in the upper right corner of the console) and then quit the program, or wait until the process has been completed.
