Question: 3. The researcher wanted to determine if there were differences between educators who chose to attend a seminar on developing technology based material and the other Field Experience groups (visit, bring, or tour) on their posttest knowledge marks (at the end of the workshop), and on their long-term composite performance indicator marks a month after the workshop.

Again, use analysis of variance (ANOVA) and the F-test to determine if there were overall differences in means. However, now if there were differences, determine if the mean of the specific group identified differs from that of the others — rather than comparing all possible pairs of means. Conduct the analyses for both the knowledge posttest and the long-term composite performance indicator for educators in the workshop using data.
