Question: 2. Now determine if there are differences among educators from the four Program Areas (English, French, Biology, or Physics) on their knowledge “posttest” marks (at the end of the workshop). Also, are there differences for the four groups on their “long-term” composite performance indicator marks administered a month after the workshop?

Again, use analysis of variance (ANOVA) and the F-test to determine if there were overall differences in means, and if there were differences, between which groups these differences occur. Conduct the analyses for both the knowledge posttest and the long-term composite performance indicator for educators in the workshop.
