How to lay it out


I know this is a basic question so sorry, but I'm trying to do some stats on mammals visiting water holes. I'm comparing 3 different months and also day vs night. I've recorded 6 x 24 hours feeds for each month and noted down the number of species and what time they visited, for 4 different locations. I'm going to look at doing some t-tests and a chi-squared (if you have any other stats recommendations, please let me know). However, I'm unsure how to lay it out on spss, like which variable going in each column. My variables would be day/night, month, and species.
