how do i compare simple slopes with two experimental conditions when to use two independent dummy codes which level is an experiment in omnibus what would be the difference between a simple slope test and a categorical predictor which is a significance difference test which two categorical predictor test for the simplest slopes of an experimental condition how to do a significance difference test between three conditions how to test the significance of two simple slopes? why do i need a statistical test to compare the simple slopes of two experimental conditions how to test significance what is the significance test in omnibus cc what is the difference between a three level categorical predictor can you use multiple conditions to test significance in omnibus can you do three level categorical predictor and two level categorical what is significance of each simple slope test how to test the significance of the slope for an experiment how to compare simple slopes what is the significance test for two simple slopes which condition based on a categorical predictor will test for significant difference what is the significance difference between two simple slopes in omnibus?
