Choose a significance level (P-value) to enter the model (SLE) and a significance level to stay in the model (SLS). Some computer packages require that SLE < SLS. Fit all k simple regression models, choose the independent variable with the largest t-statistic (smallest P-value). Check to make sure the P-value is less than SLE.

SPSS uses a single asterisk (*) to indicate whether a particular correlation is significant at the.05 level and a double asterisk (**) to indicate whether a particular correlation is significant at the.01 level. Significance indicates that it is significantly different from 0 (zero), which is the Null Hypothesis.
