 YEAR 1 YEAR 2 YEAR 3 YEAR 4 3 4 7 4 4 3 6 2 4 5 6 2 4 4 5 2 3 3 5 5 3 5 8 5 4 3 6 2 4 2 5 5 4 4 6 5 4 4 6 4 4 4 8 5 4 5 8 4 4 3 8 4 2 4 7 5 4 3 8 3 2 2 6 2 4 5 5 2 4 5 7 4 4 4 5 2 4 5 8 4 4 2 7 5 3 2 7 3 3 5 8 4 4 4 5 5 4 5 5 3 4 2 6 4 2 3 8 3 2 3 7 4 2 5 7 5 3 3 5 2 4 2 7 4 2 4 7 3 4 5 8 2 4 4 6 2 4 2 6 4 4 2 5 5 4 5 5 3 3 2 8 4 4 2 6 5 4 2 6 4 4 4 6 2 4 3 5 3 4 4 8 4 4 2 5 5 3 5 6 3 3 5 8 3 4 4 5 4 4 5 7 3 4 5 8 2 3 2 7 2 4 3 6 3 4 3 7 4 4 5 8 4 4 5 8 3 4 2 6 4 3 3 7 5 3 5 7 2 4 2 5 2 4 2 8 5 4 5 7 4 3 3 6 2

The appropriate test for this problem is:

1. t test for one sample
2. t test for dependent samples
3. t test for independent samples
4. one-way ANOVA
5. repeated measurements ANOVA

he obtained statistic value is:

1. 135.83
2. 126.67
3. 407.49
4. 669.56

The associated p value is:

1. < .1
2. < .01
3. < .001
4. < .0001

Decision is:

1. reject the null
2. retain the null

Conclusion is:

1. year 1 scores are significantly higher than the other years
2. year 1 scores are significantly lower than the other years
3. year 3 scores are significantly higher than the other years
4. year 4 scores are significantly lower than the other years
5. year 4 scores are significantly higher than year 1 and year 2
6. no conclusion can be drawn

The statistical software output for this problem is:

Hence,

1. Appropriate test: One way ANOVA

Option D is correct.

2. Obtained statistic = 124.39 [Closest to 126.67]

Option B is correct.

3. p - value < 0.0001

Option D is correct.

4. Reject the null

Option A is correct.

5. Option C is correct.
