Question

Consider a case in which two variables change together; change in the value of one is accompanied by change in the value of the other. However, the two variables have no cause-and-effect relationship. In such a case, the correlation between the two variables is said to be __________.

Answer 1

Answer:

spurious

Explanation:

When it is observed that the change in one variable corresponds to the change in another variable but the change in the first variable is not the cause of the change in the other variable.

The change in the other variable is caused due to another variable. The third variable changes due to the change in the first variable and the second variable changes due to the change in the third variable.

This type of correlation is said to spurious.
