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.
