Regression models predicting overall liking/disliking as a function of perceived astringency, bitterness and their cross product. Each row represents a separate multiple regression model. Standardized regression coefficients (β) are shown, with the p-value for that term in parentheses. P-values <0.1 are italicized and <0.05 are bolded.
