Question
If you were to construct a regression equation using the X variable to predict the Y variable for each of the three sets of data, for which set of data would the regression equation have the most negative slope? If you were to compute a correlation between the X and V variables for each of the three sets of data, which set of data would yield a correlation closest to zero? If you were to construct a regression equation using the X variable to predict the Y variable for each of the three sets of data, for which set of data would the regression equation have the largest, positive slope?Explanation / Answer
The most negative slope would be for Graph C, because as X increase, Y goes on decreasing
The correlation would be closest to Zero for Graph B, because the data points are all scattered randomly without depicting any specific trend
the largest positive slope is for Graph A, since as X increase Y also increases
