Script for t-test

Does anyone know a script that can load an excel data file and perform a t-test.

Thanks :)

If you have the Statistics Toolbox, use ttest or ttest2. So you should say whether you have the Statistics Toolbox and then whether your excel file contains data for a one-sample, paired, or two-sample t-test.

Thank you for your reply!

Yes I do have the Statistics Toolbox and the excel file contains data for a one-sample t-test. In the file there is data from 21 participants and for each of these participants there are two conditions which have 230 trials each.

Any advice of what script would work would be greatly appreciated. I have attached the excel file

Thanks again.

Sorry I confused myself a bit there; I think it is a paired sample because although I only have one sample I have two conditions. This is what I have so far:

[NUMERIC,TXT,RAW]=xlsread(EEG.data); % Open data file in Matlab

% I think somehow I need to index the 2 conditions (all of the target times and distractor times) so I can put them into the t-test (I haven't successfully managed this yet).

X=Targets Y=Distractors

[H,P] = ttest(X,Y)
