labels

Students in MAT 111 performed an experiment to see whether the perception of
the quality of peanut butter was affected by the labeling on the peanut
butter jar.  Each subject tasted from two jars, one of which was labeled
Jiff, and the other of which was labeled Great Value (a cheaper brand).
Unknown to the subjects, both jars contained Great Value peanut butter.
Each subject rated the quality of the peanut butter on a scale of 1 to 10.

datasets

This package consists of datasets and functions that are useful
    in the teaching of statistics at an elementary level to students who may
    have little or no previous experience with the command line.  The functions
    for elementary inferential procedures follow a uniform interface for user
    input. The package is typically used with package mosaic but runs
    independently of it.  Some of the functions are instructional applets that
    can only be run on the RStudio IDE with RStudio's package manipulate
    loaded. The RStudio IDE is freely available (www.rstudio.org), and includes
    package manipulate.
