To examine changes in teaching self-efficacy, 10 teachers were measured on their self-efficacy toward teaching at the beginning of their teaching career and at the end of their first and third years of teaching. The teaching self-efficacy scale ranged from 0 to 100 with higher scores reflecting greater teaching self-efficacy. The data are shown here. Conduct a one-factor repeated measure ANOVA to determine mean differences across time, using an alpha =.05. Use Bonferroni method to detect if and / or where the differences are among the time points.
