A Multiple Regression Model Has the Form ŷ = B₀

question 69

Multiple Choice

A multiple regression model has the form ŷ = b₀ + b₁x₁ + b₂x₂. Which of the following best describes b₂?

• A) We estimate for each one unit increase in x₂, that y will increase by b₂ units, on average.
• B) Whilst holding x₁ constant, we estimate for each one unit increase in x₂, that y will increase by b₂ units, on average.
• C) Whilst holding x₂ constant, we estimate for each one unit increase in x₁, that y will increase by b₂ units, on average.
• D) Whilst holding x₁ constant, we estimate for each one unit increase in x₂, that y will increase by b₁ units, on average.

Definitions:

Alternating Treatments Design

An experimental design in behavior analysis that allows the comparison of two or more interventions by alternating them in a rapid succession to observe their effects on behavior.

Functional Relation

The relationship between a specific behavior and the environmental conditions that reliably influences the occurrence of this behavior.

Gradual Behavior Change

A slow and systematic modification of behavior patterns over time.

Multiple Baseline Design

An experimental design that introduces the intervention at different times across settings, behaviors, or subjects to demonstrate control over the variables being examined.
