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 1st and 3rd 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 measures ANOVA to determine mean differences across time, using α = .05. Use the Bonferroni method to detect if and/or where the differences are among the time points.
