Question

Match each scatter plot shown below with one of the four specified correlation coefficients. b. 0.25 c.-0.40 d. 0.85 o% o Q o Oo O lo

Answer 1

1. For the first scatter plot, the liner function is decreasing. So the correlation coefficient would be negative and the answer would be -0.4

2. For the second scatter plot, we can see there is a perfect negative correlation and the answer would be -1

3. For the third scatter plot, the liner function is increasing. When the values of X is increasing then the values of Y is also increasing. So the correlation would be positive and we have two options 0.25 and 0.85. But here the coefficient would not be 0.85 because of last scatter plot. Final answer would be 0.25.

4. For the fourth scatter plot, the liner function is increasing. When the values of X is increasing then the values of Y is also increasing. Here the correlation correlation would be closer to 1. Final answer would be 0.85
