Several high schools participated in a study to evaluate the effectiveness of a new computer-based math curriculum. In all these high schools combined, there were twelve 24-student sections of freshman algebra available for the study. The computer-based curriculum was assigned to six of the sections, chosen at random from the twelve sections. The standard curriculum was assigned to the remaining six sections. At the end of the term, a standard math achievement test was given to each of the 24 students in each section.
Required:
a. Is this study experimental, observational, or mixed experimental and observational? Why?
b. Identify important factors, factor levels, and/or factor-level combinations.
c. Classify these factors as within- or between-subjects
d. What’s the dependent measures?
e. What is the basic experiment unit of study?
