WebIn this practical we are going to investigate how to perform a Mann Whitney test using SPSS. A Mann-Whitney test is used when we have a continuous level variable measured for all observations in two groups and we want to test if the distribution of this variable is different in the two groups but we are unable to assume normality in both groups. WebThe test is based on the fact that when data are normally distributed the test statistic zs = skew/s.e. has a standard normal distribution where skew = the skewness of the sample data and the standard error is given by the following formula where n = the sample size. Example 1: Conduct the skewness test for the data in range B4:C15 of Figure 1.
