Background and Data

Generation The normal random numbers used in this case study are from a Rand Corporation publication.

The motivation for studying a set of normal random numbers is to illustrate the ideal case where all four underlying assumptions hold.

Software The analyses used in this case study can be generated using both Dataplot code and R code.
Data The following is the set of normal random numbers used for this case study.
