Question 1

Question
Statistical tests are needed to tell us whether there is enough evidence to accept or reject the alternative [blank_start]hypothesis[blank_end]. The p-value is nearly always [blank_start]<0.05[blank_end]. Mann Whitney, Wilcoxon and [blank_start]Chi Squared[blank_end] are used in tests of difference. [blank_start]Spearman's Rank[blank_end] is used in tests of association or correlation. Mann Whitney is used when the data is [blank_start]ordinal[blank_end] and when the experimental design is [blank_start]independent groups[blank_end]. [blank_start]Wilcoxon[blank_end] is used when the data is ordinal and when the experimental design is a repeated measures or [blank_start]matched pairs[blank_end]. Chi Squared is used when the data is [blank_start]nominal[blank_end] and the experimental design is an [blank_start]independent groups[blank_end] design. Spearman's Rank is used when the data is [blank_start]ordinal[blank_end] and the test is of [blank_start]association or correlation[blank_end]
