Hierarchical regression is usually used in the study of mediation or adjustment.

When analyzing, personal basic information items or control variables are usually placed in the first layer; The second layer is the core research project. The results of online SPSS analysis using spssAU are as follows:

r? : explanatory power of the model

F value: used to judge whether the model is meaningful. If the corresponding p value is less than 0.05, the model is meaningful.

△R? : when the model changes, r? Changes in value

△F value: when the model changes, the value of f also changes (this value is not directly subtracted from the value of f). If the corresponding p value is less than 0.05, it means that the model change is meaningful and can be specified by △R? Check the model that explains the intensity change, and check the significance of the newly added independent variables. Concrete analysis can lead to intelligent text analysis and interpretation.
