In this example the Spearman's coefficient of rank correlation rho is 0.114.  The 95% confidence interval 

ranges from  0.084 to 0.304. The associated P value is 0.255 and the conclusion therefore is that there is 

not a significant relationship between the two variables.

Scatter diagram 

In a scatter diagram, the relation between two numerical variables is presented graphically.  One variable 

(the variable X) defines the horizontal axis and the other (variable Y) defines the vertical axis.  The values 

of the two variables on the same row in the data spreadsheet, give the points in the diagram. 

You can click the 

 button to obtain a list of variables.  In this list you can select a variable by clicking the 

variable's name.  Optionally, you may also enter a selection criterion in order to include only a selected 

subgroup of cases in the graph.   

You can select a logarithmic transformation for one or both variables (in this case the program will use a 

logarithmic scale for the corresponding axis in the graph).   

Use the Subgroups button if you want to identify subgroups in the scatter diagram.  A new dialog box is 

displayed in which you can select a categorical variable. The graph will display different markers for the 

different categories in this variable. 

After you select the 

OK

 button, or press the Enter key you obtain the following graph: 

This is the same scatter diagram, but the categorical variable  Treatment  has been used to identify 

different subgroups in the graph.
