Hello All,

 

I am facing bit tricky situation. I frequently run statistical
significance testing, column means and column proportions in custom
table. As a rule of thumb, I understand that we should not do
significance testing if n (base) is less than 30. However, SPSS will
still generate the p-values and significance testing even being the
valid n less than 30. Is there any way, to set benchmark for SPSS,
available to set rule of comparing groups and generating stat testing
only if the valid n of groups are more than 30?

 

Any help will be of great help.

 

Regards,
