Age as covariate textfile in two sample t-test
Hi,
I want to calculate a two sample t-test and include age as covariate. Is it correct to just add two textfiles in the Text covariates menu in the same order as my groups in Group images. The textfiles for every group have the covariate (age) for every person in the rows in the same order as the images of the subjects?
For example
Group Images | Text Covariates
Group1 | AgeGroup1.txt
