Question

When only two treatments are involved, ANOVA and the Student's t test (Chapter 11) result in the same conclusions. Also, for computed test statistics, t-F. To demonstrate this relationship, use the following example. Fourteen randomly selected students enrolled in a history course were divMded into two groups, one consisting of 6 students who took the course in the normal lecture format. The other group of 8 students took the course as a distance course format. At the end of the course, each group was examined with a 50-item test. The following is a list of the number cormect for each or the two groups Traditional Lecture Distance 36 31 38 45 35 45 35 49 42 a-1. Complete the ANOVA table (Round your SS, MS, and F values to 2 decimal places and value to 4 decimal places.) Source Factors Error Total df MS

Explanation / Answer

a-2 critical F = 4.747225

b) t =-2.258769757

c)

as p-value = 0.043306904 < 0.05

Reject Ho , there is difference in the mean

Traditional Lecture Distance 36 45 31 35 38 45 31 35 31 49 40 33 42 42
