A Wilcoxon Signed-Ranks Test was conducted to compare pre-test and post-test ranks. The results indicated that post-test ranks were statistically significantly higher than pre-test ranks, with a Z score of 21 and p value less than .027. The document provided guidance and examples for reporting the results of the Wilcoxon Signed-Ranks Test in APA style.

1. Reporting the Wilcoxon
Signed-ranks Test

2. Template:

3. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.

4. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
Here’s the Data Set from
SPSS:

5. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.

6. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
This is the
ranking of each
student on a
pre-test
compared to a
national norm

7. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
This is the
ranking of the
same
students on a
post-test
compared to a
national norm

8. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
After running a Wilcoxon
Signed-Rank Test here is
the output:

9. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.

10. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
A Wilcoxon Signed-Ranks Test indicated that post-test ranks
were statistically significantly higher than pre-test ranks
Z = 4.21, p < .000.

11. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
A Wilcoxon Signed-Ranks Test indicated that post-test ranks
were statistically significantly higher than pre-test ranks
Z = 4.21, p < .000.

12. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
A Wilcoxon Signed-Ranks Test indicated that post-test ranks
were statistically significantly higher than pre-test ranks
Z = 4.21, p < .000.

13. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
A Wilcoxon Signed-Ranks Test indicated that post-test ranks
were statistically significantly higher than pre-test ranks
Z = 21, p < .027.

14. A Wilcoxon Signed-Ranks Test indicated that [Insert Time 2
of Independent Variable] was statistically significantly
higher than [Insert Time 1 of Independent Variable]
Z = ____, p < .____.
A Wilcoxon Signed-Ranks Test indicated that post-test ranks
were statistically significantly higher than pre-test ranks
Z = 21, p < .027.

15. The report in APA
A Wilcoxon Signed-Ranks Test indicated that the median post-
test ranks were statistically significantly higher than the median
pre-test ranks Z = 21, p < .027.

16. The report in APA
A Wilcoxon Signed-Ranks Test indicated that the median post-
test ranks were statistically significantly higher than the median
pre-test ranks Z = 21, p < .027.
1st Note – You may be asked to report the
median of each ranked variable. It this is the
case go to descriptive statistics in SPSS and
select Median. Do this for both variables:

17. The report in APA
A Wilcoxon Signed-Ranks Test indicated that the median post-
test ranks were statistically significantly higher than the median
pre-test ranks Z = 21, p < .027.
For example:

18. The report in APA
A Wilcoxon Signed-Ranks Test indicated that the median post-
test ranks, Mdn = 34.5, were statistically significantly higher
than the median pre-test ranks, Mdn = 25.5, Z = 21, p < .027.

19. The report in APA
A Wilcoxon Signed-Ranks Test indicated that the median post-
test ranks were statistically significantly higher than the median
pre-test ranks Z = 21, p < .027.
2nd Note – if the reason you used a Wilcoxon
Signed Ranks Test is because your data is very
skewed or non-normal, just report it the same
way but replace ranks with scores

20. 2nd Note– if the reason you used a Wilcoxon
Signed Ranks Test is because your data is very
skewed or non-normal, just report it the same
way but replace ranks with scores
The report in APA
A Wilcoxon Signed-Ranks Test indicated that post-test ranks
were statistically significantly higher than pre-test ranks
Z = 21, p < .027.
Because the data was skewed for one of the variables, a
Wilcoxon Signed-Ranks Test was run and the output indicated
that post-test scores were statistically significantly higher than
pre-test scores, Z = 21, p < .027.
