The data used in Chapter 11, Table 5
An object of class
data.frame with 12 rows and 4 columns.
The data show that 12 participants have been observed in each of 4 conditions. To make the example easier to discuss, let's suppose that the 12 subjects are children who have been observed at 30, 36, 42, and 48 months of age. Essentially, for the present data set, 12 children were each observed four times over an 18 month period. The dependent variable is the age-normed general cognitive score on the McCarthy Scales of Children's Abilities. Interest is to determine if the children were sampled from a population where growth in cognitive ability is more rapid or less rapid than average.
age-normed general cognitive score for 30-month-old
age-normed general cognitive score for 36-month-old
age-normed general cognitive score for 42-month-old
age-normed general cognitive score for 48-month-old
