1) Which of the following is not true about the correlationbetween two numerical variables?
The correlation coefficient is always between -1 and 1, bothinclusive.
If the correlation coefficient is positive, in general, y valuesincrease as x values increase.
Strong correlation always gives positive value close to1
If there is no correlation between two variables, correlationcoefficient will be close to zero.
2) Which correlation coefficient reflects thestrongest linear relationship?
0.825
0.089
-0.879
-0.445
