Teaching descriptive statistics. A study compared five different
methods for teaching
descriptive statistics. The five methods were traditional lecture
and discussion, programmed textbook instruction, programmed text
with lectures, computer instruction, and computer instruction
with lectures. 45 students were randomly assigned, 9 to each
method. After completing the course,
students took a 1-hour exam.
(a) What are the hypotheses for evaluating if the average test
scores are different for the different
teaching methods?
(b) What are the degrees of freedom associated with the F-test for
evaluating these hypotheses?
(c) Suppose the p-value for this test is 0.0168. What is the
conclusion?
