1. Answer :
1) H0 : µ1 + µ2 + µ3
Ha: At least one group mean differ
2) Make a decision based on SPSS output:
“There was a signification effect of types remembered at the p<0.05 level for three
conditions (F (2, 12) = 13.38 , p = 0.001).”
Answer:
Group 1 (Group 1 and Group 2) : p < 0.009 (statistically significant)
Group 2 (Group 1 and Group 3) : p < 0.000 (statistically significant)
Group 3 (Group 2 and Group 3) : p < 0.042 (statistically significant)

2. Answer:
a) - Its use when we look at more than two groups of data and compare them.
- It help to find out if the means for each group / condition are significantly different
from one another or if they are relatively the same.
b) H0 : µ1 + µ2 + µ3
Ha: At least one group mean differ
c) Make a decision based on SPSS output:
“There was a signification effect of teacher’s experience remembered at the p<0.05 level
for three conditions (F (2, 47) = 15.69 , p = 0.000).”
d) Post hoc comparisons using the Tukey HSD test indicated that the mean score for 1-5
years experience (M= 41.60, SD= 5.77) did not significantly differ from the 6 -10 years
experience (M= 47.90, SD= 5.07) and 11-15 years experience(M= 37.00, SD= 4.64)

3. Group 1 (1-5 years and 6-10 years) : p < 0.000 (statistically significant)
Group 2 (1-5 years and 11-15 years) : p < 0.029 (statistically significant)
Group 3 (6-10 years and 11-15 years) ) : p < 0.000 (statistically significant)
