It depends on your findings. This section describes the procedure that can be used to find out whether the correlations for the two groups are significantly different. The CTABLES or Custom Tables procedure, if you have access to it, will let you create a crosstabulation like you mention, and then will let you test both for any changes First we will be converting the r values into z scores and then we use an equation to calculate the observed value of z (zobs value). First step is to convert the correlation coefficients (r) into the Z scores. SPSS calculates an F-statistic (ANOVA) or an H-statistic (Kruskal-Wallis) with Ehsan Namaziandost , kindly elaborate on how you concluded that the time is statistically significantly lower in this statement, "A Tukey post hoc If 1.96 < zobs < 1.96: correlation coefficients are not statistically significantly different.

This is how the dialog box needs to be set up. Put these values into the equation to calculate zobs. The following procedure selects the part of the dependent data that right. You can accomplish this task using the Compute Variable dialog box. This is the ANOVA table; F-ratio and P are on the Its this way around because we want a positive number (representing an increase) if the posttest score is higher than the pretest score. The products are always creative, high quality and arrive in good condition. What we want to do here is to create a new variable that holds difference scores (or change scores) for our pretest and posttest variables. Overall awesome brand. + 1/N(J)) Males r1 =.262 N1 =235, Females r2 =.293 N2 =30. However, if you have two groups, youll typically use a two-sample t-test. I look forward to the handwritten cards. As you can see, SPSS has created a new variable called Change, and filled it with difference scores (i.e., calculated by subtracting the PrePEF score from the FirstPostPEF score). From the menus choose: Analyze > Compare Means > Independent-Samples T variable. This is currently set at 2, whereas the other variables are configured to display without decimals. *.
