Define the following test statistics for samples 1 and 2 where n 1 is the size of sample 1 and n 2 is the size of sample 2, and R 1 is the adjusted rank-sum for sample 1 and R 2 is the adjusted rank-sum of sample 2. One-tailed - the relationship between the variable is in one specific direction. The Mann-Whitney U test is essentially an alternative form of the Wilcoxon Rank-Sum test for independent samples and is completely equivalent. Among medical social workers, females and males will differ in their job-satisfaction levels Two-tailed - the relationship between the variables goes in either direction, meaning that the test is determining if there is one variable that has an overall effect on the other variable. Rejection level – Selected probability level at which the null hypothesis is rejected Null hypothesis – The statement that there is no relationship between two variables of interest As you can see above, the value of the Fisher’s exact test statistic. You can view the test result in the SPSS output viewer. Press Continue, and then OK to run the test. One-sample z-test (u-test): This is a hypothesis test that is used to test the mean of a sample against an already specified value. Hit the Exact button (top right within the Crosstabs dialog), and choose the Exact option, leaving the test time limit as it is. Population size – In statistics, all individuals, objects, or events that meet the criteria for study PARAMETRIC TESTS The various parametric tests that can be carried out are listed below.
