What is another name for hierarchical regression?

• A. Hierarchical regression
• B. Blockwise regression
• C. Stepwise regression
• D. Canonical regression

Answer: (B)

In hierarchical regression, you enter predictors in blocks or groups in a predefined order, based on theory or research questions, and you examine how much additional variance each block explains beyond the previous ones. This approach is also called blockwise regression because the predictors are added block by block rather than one variable at a time or by automatic selection. The idea is to see the incremental contribution of each theoretically defined set of predictors to the outcome. So this question uses blockwise regression as the synonym for hierarchical regression. Stepwise regression, in contrast, adds or removes variables automatically based on statistical criteria rather than theory, and canonical regression deals with relationships between two sets of variables rather than block-entry in a single regression model.
