Scenario Analyze the experimental results of Study Type on Learning

Randomly assign participants to either a distributed or massed practice study type. When the study sessions are completed, administer a test to assess learning. Then examine any potential differences in the mean amount of material learned.

First read the data table, also available from within the lessR package called Learn.

> mydata <- Read("Learn", format="lessR")

An excerpt of the data, as it exists in the data frame mydata, is shown in Listing 6.13, with the variables StudyType and Score.
