Question 1 (1 point) Match the symbols with the correct definitions. T a, b A statistic that measures the percentage of total variation in 1, the response variable that is explained by the linear relationship with the explanatory variable. The value is literally the square of the correlation coefficient. Symbol for correlation coefficient, where values range from -1 to 1 and are unitless, values close to -1 and 1 denote a strong linear relationship; values close to 0 denote a weak or no linear relationship. 3. The predicted value for the response variable 4. The intercept and slope coefficients for a regression line.

Explanation / Answer

Sol:

Y^=predictive value of response variable
