Dear All,
My colleague has some data which it is suggested should be analysed for
differences using a 'Planned Contrast test'. Other names for this are
'Orthogonal test' or 'a priori test'.
I have not come across this before, but apparently it is a routine available
in SPSS (which i do not have access to). Is this simialr to Scheffes Test.
If not, could anybody tell me a bit more about it and provide a reference.
Thanks in advance
Alan Sharpe
