Hello all statistics altruists - I have run a between subjects experiment testing subjects' speed of dialling from a mobile phone under 2 different conditions. 12 subjects each dialled the same 10 names under both conditions and i want to do run t-tests in SPSS to see if there is an effect of condition on dialling time.
I am pretty sure that i need to be running a 2-tailed "paired samples" t-test in SPSS to do the analysis i want. The problem is i am not sure that i have set out my data correctly for this. At the moment i have 2 columns representing the 2 conditions. Each column contains 120 rows of data (12 subjects x 10 dial attempts). I then choose [column 1 vs column 2] in the "paired samples t test" box of SPSS. Is this correct? I have the feeling that this set out may be treating the data as if there were 120 participants instead of 12. Im not even sure if this makes any difference, but i am a novice with very little available support and i just wanted to make sure. thanks very much to any replies.
