A study of reading comprehension in children compared three
methods of instruction. The three methods of instruction are called
Basal, DRTA, and Strategies. As is common in such studies, several
pretest variables were measured before any instruction was given.
One purpose of the pretest was to see if the three groups of
children were similar in their comprehension skills. The READING
data set described in the Data Appendix gives two pretest measures
that were used in this study. Use one-way ANOVA to analyze these
data and write a summary of your results.
