Question

Two researchers analyse the exact same data set, using multiple regression analyses to predict depression from secure attachment, neuroticism, and anxiety. Catherine finds that anxiety is a significant predictor of depression in her analysis, while Sam finds that anxiety is not a significant predictor in her analysis. Assuming neither made a mistake, which of the following is true about how the researchers conducted their analyses?

(a) Sam must have conducted a standard multiple regression (SMR); while Catherine must have conducted a hierarchical multiple regression (HMR), entering secure attachment and neuroticism in Block 1, and anxiety in Block 2.

(b) Catherine must have conducted a standard multiple regression (SMR); while Sam must have conducted a hierarchical multiple regression (HMR), entering anxiety in Block 1, and secure attachment and neuroticism in Block 2.

(c) Sam must have conducted a standard multiple regression (SMR); while Catherine must have conducted a hierarchical multiple regression (HMR), entering anxiety in Block 1, and secure attachment and neuroticism in Block 2.

(d) Catherine must have conducted a standard multiple regression (SMR); while Sam must have conducted a hierarchical multiple regression (HMR), entering secure attachment and neuroticism in Block 1, and anxiety in Block 2.

Answer #1

**(c) Sam must have conducted a standard multiple
regression (SMR); while Catherine must have conducted a
hierarchical multiple regression (HMR), entering anxiety in Block
1, and secure attachment and neuroticism in Block 2.**

Anxiety as single predictor would be a significant predictor of depression. But Anxiety in multiple regression model with secure attachment, neuroticism may not be a significant predictor. This may be because the variation of depression due to Anxiety is explained by secure attachment, neuroticism.

Two researchers are analysing the exact same data set, using
multiple regression analyses to predict depression from secure
attachment, neuroticism, and anxiety. Jo decides to
conduct a standard multiple regression (SMR). Daniel
decides to conduct a hierarchical multiple regression (HMR) with
neuroticism and secure attachment in Block 1, and anxiety in Block

both researchers. Which of the following statements must
be true about the relationships among the independent
variables?
