Just a basic question. Apologies if it seems as though I am repeating
myself a bit from a previous question kindly answered by Marta Garcia-
Granero, but this is just a small clarification.
I simply want to carry out a test for trend to see if uptake of breast
cancer screening (screened or not screened) differs according to age
(four groupings from lowest to highest ages). I have obtained the linear-
by-linear association chi square value in SPSS and just want to know the
name of this test. Is it just a chi square test for trend or is it
the 'Mantel-Haetszel test for trend'?
