Document Summary
Determines whether differences exist between population means. Procedure works by analyzing the sample variance. Procedure that tests to determine whether differences exist between two or more population means. Technique analyzes the variance of the data to determine whether we can infer that the population means differ. Experimental design is a determinant in identifying the proper method to use. Procedure to apply when the samples are independently drawn. Figure 14. 1: sampling scheme for independent samples page 526. Confirm that the data are interval and that the problem objective is to compare populations. Parameters are the four* population means: and. Null hypothesis will state that there are no differences between the population means. Analysis of variance determines whether there is enough statistical evidence to show that the null hypothesis is false. Alternative hypothesis will always specify the following: Next step is to determine the test statistic. The variable x is called the response variable. The values of the response variable x.
