Wilcoxon Z Score. See Section 72 of BBR which discusses a simple accurate z test statistic for the Wilcoxon signed-rank test. From these we calculate a z-score of 257 cell K12 which yields a p-value cell K14 of01 two-tail test which is less than α 05 and so once again we reject the null hypothesis.
The official way for reporting these results is as follows. In particular it is suitable for evaluating the data from a repeated-measures design in a situation where the prerequisites for a dependent samples t-test are not met. Z equals the sum of signed ranks divided by the square root of the sum of their squares.
In particular it is suitable for evaluating the data from a repeated-measures design in a situation where the prerequisites for a dependent samples t-test are not met.
The Wilcoxon test evaluates differences between paired scores either repeated or matched. The median difference is positive α005. May 04 2017 Similar to the Sign Test hypotheses for the Wilcoxon Signed Rank Test concern the population median of the difference scores. In particular it is suitable for evaluating the data from a repeated-measures design in a situation where the prerequisites for a dependent samples t-test are not met.
