Interpreting Significance (and insignificance)

Interpreting Significance (and insignificance)

As with our other tests, you can assess the significance of a coefficient by looking at its p-value. While our critical value of .05 is somewhat arbitrary, output in R will mark tests that are statistically significant at the .05 level with at least one *. 

Remember: tests with p values of greater than .05 do not provide enough evidence to conclude that there is or is not a relationship or effect. 

Note: Be careful when interpreting the magnitude and direction for insignificant coefficients. 

Note: We often designate significant effects using parentheticals at the end of the sentence (i.e., p < .05)
