In a scatter diagram if one of the points does not fall on t
In a scatter diagram, if one of the points does not fall on the straight line of best fit to the data points, then r cannot be
0.
+1.00 or -1.00.
Positive.
Negative.
| a. | 0. | |
| b. | +1.00 or -1.00. | |
| c. | Positive. | |
| d. | Negative. |
Solution
If all points falls on the straight line of best fit, then the correlation between variables will be strictly positive/ strictly negative, with correlation coefficient as -1 or +1
If any one of the points does not fall on the straight line of best fit to the data points, then \'r\' cannot be +1 or -1
Ans: B
