n another analysis from the same study of nurses, perceived pressure was compared across the three work areas.

            Using the results of the Tukey test below, which groups did and did not differ and in which direction? i.e., who seemed to feel their pressure were relatively higher? Lower? (5 point)

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 READINGdata set described in the Data Appendix gives two pretest measures that were used in this study. Use one-way ANOVA...
