Thank you it worked but now the calculator says that the means are different. And that t is higher than the critical value. Does this mean that the null hypothesis is rejected?

I'm sorry SO much to keep insisting. But is it two-tailed, or one-tailed. Why? I seriously don't understand I've looked for the answer but I don't get it.

Sorry to bother, but do you think you could do a brief explanation for it? Also my sample consists of 37 participants.

I thought the t-test was for independent measures only.

For my Psychology IA, I conducted a study in which I told participants to read out loud a list of words, the words were color names printed in black (this is condition one) and wrote down the time they took to complete the task. Then, I gave them another list of words, but printed in colors different than what their names pronounced (for example: red, green, blue), this was condition two. There are no control groups or experimental groups since every participant went through both conditions. However, I'm having trouble in the inferential statistics criteria for my paper. I don't know what test to use. Please help.
