Gawra is a leading beauty company selling direct. It is Important to remember, when you are finished looking at males and females separately you will need to turn the Split File option off. We'll use both Split File methods so that we can compare what their outputs look like. Thank you everybody specially Ehsan Namaziandost . To split the data in a way that will facilitate group comparisons: After splitting the file, the only change you will see in the Data View is that data will be sorted in ascending order by the grouping variable(s) you selected. Unfortunately, SPSS will not do this step for you, so it is done manually. At a glance, we can quickly take note that in this sample: Note: This combination of Split File: Compare Groups with Descriptives is very similar to what you would get with the Compare Means procedure. There are certain products that may not seem essential, but on application give you an all new look. You can use Kruskal-Wallis followed by Mann-Whitney. Alternatively, Spearman Correlation can be used, depending upon your variables. These are comm From the output given above, the correlation between ATIB and SI for males was r=.262, while for females it was slightly higher, r=.293.

This can be useful when you want to compare frequency distributions or descriptive statistics with respect to the categories of some variable (e.g., Gender) - especially if you want separate tables of results for each group. + 1/N(J)) I look forward to the handwritten cards. Perhaps the most common scenario for computing difference scores is where youve got a pre-test/post-test scenario, and you want to see how the dependent variable has changed between the two conditions (difference scores are sometimes termed change scores). Comparison Do you want a single table with all results, or separate tables for each group's results? We want to create an additional variable that holds the difference scores for these two variables allowing us to track how peak flow has changed after treatment.
