Kruskal Wallis 5 of 26 What is Mann Whittney U's design? Look at the difference between treatments in a between groups design 6 of 26 When would you expect the null hypothesis to be true The data to be randomly distributed 7 of 26 When would you expect the null hypothesis to be false? If the scores of the true groups was clustered at either end of the sequence 8 of 26 How do you work out Mann Whittney U? you use the larger rank and then apply it to the equation 9 of 26 When do you reject the null? Observed is smaller or equal to the Critical 10 of 26 Where is the Mann Whittney U test found in SPSS? Analyse/IndependentSamples/then click Mann Whittney U 11 of 26 What is the Wilcoxon Related Samples designed to look at? Differences between treatments in within subject design 12 of 26 What do you do in the test? work out the difference, add up the positive and minuses, rank them, then use the smallest T 13 of 26 When is the null hypothesis rejected? Observed is higher than critical 14 of 26 What happens when you have tied ranks? Work out the average of the range of ranks that the ties cover and allocate this to the value of the ties 15 of 26 What happens when you get a zero difference score? All of the subjects get removed from the analysis. simply reduce N by the number of subjects where this happens 16 of 26 Where is the Wilcoxon test found in SPSS? ANalyse/Non parametric test/2 related samples 17 of 26 What does a Kruskall Wallis test look at? Differences between treatments in a between groups design 18 of 26 What do we expect when the null hypothesis is true? random distribution of ranks across groups 19 of 26 What do we expect when the null hypothesis is false? systematic distribution of ranks across groups 20 of 26 Where is Kruskall Wallis Test found baby? Analyse/nonparametric test/kindependentsamples 21 of 26 What is Friedman's test designed for? Paired samples, in both within subject and matched design 22 of 26 What happens in the experiment first? The data is ranked 23 of 26 What is the test statistic? X2 R 24 of 26 Where is it found in SPSS? Analyse/Nonparametric/Krelated samples 25 of 26 Why do we use a bonferroni test? Does not tell us which conditions differ 26 of 26
