A study of reading comprehension in children compared three
methods of instruction. The three methods of instruction are called
Basal, DRTA, and Strategies. Basal is the traditional method of
teaching, while DRTA and Strategies are two innovative methods
based on similar theoretical considerations. The READING data set
includes three response variables that the new methods were
designed to improve. Analyze these variables using ANOVA methods.
Be sure to include multiple comparisons or contrasts as needed.
Write a report summarizing your findings.
