My operating system is windows 7, I'm using SPSS version 22 and the data I'm trying to analyse is times of a race. I have the results of a Triathlon from earlier this year. I want to compare the Men's 30-34 Standard Distance overall times with that of the Female 30-34 Standard Distance overall race times. I have used the top 20 from each race so I have the same number of people in each category.
To do this I went into variable view and in the first row under name have entered 'Gender' which I have specified is a numerical type. I gave the value of 1 for the males and 2 for the females. I then went back into data view and in the first column typed in 1 twenty times followed by 2 twenty times. I then went back into variable view and in the 2nd row entered 'Time' which I have specified as a date type, specifically hh:mm:ss as this is the format the information was recorded in. I then switched back to data view and entered the times in the second column. Both data are set to nominal measures.
I tried then running an independent t-test. I entered 'Time' as the test variable and 'Gender' as the grouping variable and specified that males = 1 and women = 2 in the define groups option. I press ok and it runs the test and it is giving me nukbers for everything but the Sig. (2-tailed) box which is appearing as .000
