WebIf a model term is statistically significant, the interpretation depends on the type of term. The interpretations are as follows: If a continuous predictor is significant, you can conclude that the coefficient for the predictor does not equal zero. If a categorical predictor is significant, you can conclude that not all the level means are equal. WebThe interpretation continues to be a simple visual assessment. Zero represents no difference between the means. Does the interval contain zero? If it does not include zero, the difference is statistically significant because the range excludes no difference. At a glance, we can tell that the difference is statistically significant.
