7. Use tables of critical values for the Wilcoxon signed rank sum test to find the probability of observing a value of W or more extreme. Most tables give both one-sided and two-sided p-values. If not, double the one-sided p-value to obtain the two-sided p-value. This is an exact test. Normal approximation
Find the critical values for the Wilcoxon signed-rank test at different sample sizes and levels of significance. Compare the test statistic with the values in the table to reject or accept the null hypothesis of identical populations.

Critical Values for T in theWilcoxon Signed Mixed-Pairs Signed-Rank Test The values below are the approximate critical values of T for two-tailed tests at level P. For a signicant result, the calculated T must be less than or equal to the tabulated value. (Values of P are halved for one-tailed tests using R− and R+.) n P = 0.10 P = 0.05 5 2 ...

The Wilcoxon Signed Rank Test examines the signed differences between each reading and the suggested population median or mean N.B. This is a more accurate version of the sign test but can only be used if ... Critical Value: Taken from Table 10 in the formula booklet Compare: - Draw a line from 0 to ∞ - Mark the critical value from Table 10
The critical value in the table is 25: my obtained value is smaller than this, and so I would conclude that the difference between the two conditions in my study was unlikely to occur by chance (p<.05 two-tailed test, or p<.025, one-tailed test).

The document provides information about the Wilcoxon signed-rank test, a nonparametric statistical hypothesis test used to compare two related samples, matched samples, or repeated measurements on a single sample to assess whether their population mean ranks differ. It includes an example of midterm and final exam scores for 10 students and the critical values table used to determine if the ...
Tabel Wicoxon - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document provides a critical values table for the Wilcoxon Signed-Rank Test. It lists sample sizes from 5 to 30 across the top and various significance levels (α = 0.05, 0.025, 0.01, 0.005) down the left side. The body of the table gives the critical test value that corresponds to rejecting the ...
