The coefficient of determination, also known as R-squared, estimates the proportion of variability in one variable that can be explained by another variable in a regression model. In this case, the firmness of handshake is the predictor variable and the positivity of first impressions is the outcome variable. Therefore, the coefficient of determination would estimate the amount of variability in first impressions ratings that can be accounted for by handshake firmness.
