The unstandardized regression coefficient is typically denoted by which symbol?

• A. bi
• B. βi
• C. α
• D. γ

Answer: (A)

The unstandardized regression coefficient tells you how much the dependent variable changes for a one-unit change in a predictor, using the original units of both variables. The symbol used for this slope for predictor i is b_i (bi with subscript i). This distinguishes it from the standardized coefficient, which is β_i and uses z-score units, making different predictors directly comparable. The intercept is typically denoted by α (or a), not the slope, and γ is used in other contexts. So the unstandardized slope for predictor i is represented by b_i.
