I am doing research on performance pressure and gender and I have the task scores of both men and women in a low pressure setting and a high presure setting. Both men and women had lower scores in the high pressure setting, how do I find out if there is a significant difference between their reductions?
The simplest method is an independent samples t-test on the change scores. A bit more sophisticated, is analysis of covariance, where the dependent variable is the scores for the high pressure setting, and the covariate, the scores for the low pressure setting. The most complex analysis is a linear mixed effects model.
Thanks Adrian. I tried the Ancova and this was my result
Source Sig.
LpScore .000
Gender .450
Does that mean the difference between someone's low pressure score and high pressure is statistically significant but it is not between the genders (sig set at .005)?
Simply try the two - independent samples t-test on the change scores. I did not get your setting for the ANCOVA.
