applying 2 way ANOVA on above data:
| Source of Variation | SS | df | MS | F |
| treatments | 25.44 | 2 | 12.72 | 7.11 |
| blocks | 37.11 | 5 | 7.42 | |
| Error | 17.89 | 10 | 1.79 | |
| Total | 80.44 | 17 |
test statistic =7.11
critical value =4.10
p value =0.0120
reject the null hypothesis: Yes
Conclusion: conclude that there is a signifcant difference between treatment means
