Answer: Third table shows no correlation.
Explanation:
- The term correlation tells that the two variables are related or not.
- If two variables are not interdependent such that if one increasing then there is no proportional change in the other variable, then we say there is no correlation.
Table 1 shows that as values of x increasing, the values of y decreasing .
⇒ There is negative correlation.
Table 2 shows that as values of x increasing, the values of y increasing .
⇒ There is positive correlation.
Table 4 shows that as values of x increasing, the values of y decreasing .
⇒ There is negative correlation.
From the third table, it can be seen that the values x is increasing but the values of y first increasing then becomes equal at 6 and 8 but decreasing after it.
It shoes that the variables are not interlinked .
Thus third table shows there is no correlation between the variables.
