Selecting the appropriate statistical analysis and sample size is a very common problem for graduate students. Here is the strategy we use at Statistics Solutions: select the correct test, and then select the correct sample size for that test. First, you have to define the level of measurement of each variable to be included in the analysis. Your variables will be categorical or nominal, ordinal or rank-ordered, interval, or ratio-level. This needs to be done for both your independent and dependent variables.
