I have a variable in SPSS that is named "program" which has four groups; biology, physics, french, and english. Students were assigned different programs and were tested (initial test scores). How do you use analysis of variance (ANOVA) and theF-test to determine if there were overall differences in average marks for educators in the four Program Area groups. If there were differences, between which groups did these differences occur (post hoc tests)? how do I conduct the analyses for both the initial knowledge test and the composite performance indicator for educators in the workshop using data from.
