Only include numbers of scores which are difference from each other

Question 3

When are the results significant in wilcoxon test?

Answer 3

If the T value is less than or equal to the critical value

Question 4

What do you do once you have the given T value in wilcoxon test?

Answer 4

Look at the critical values table and look at the value at N (results with different scores) at P=0.05 depending on whether it is a one tailed or two tailed hypothesis

Question 5

What conclusions can you draw if the calculated value at T is smaller than the critical value in wilcoxon test?

Answer 5

The results are statistically significant
Reject the null hypothesis
Accept the alternative hypothesis

Question 6

What conclusions can you draw if the calculated value at T is greater than the critical value in wilcoxon test?

Answer 6

The results are not statistically significant
