Variable x is the number of students trained on new projects, and variable y is the number of calls to the other institute. You suspect that some training increases the number of calls and some training decreases the number of calls. Does this follow a positive correlation or negative correlation?

The correct answer is that this follows neither positive nor negative correlation. Thus this follows no correlation.

Step-by-step explanation:

Correlation is the measure of how two variables are dependent on one another. Positive correlation means that increase in one variable increases the other. Whereas negative correlation means that increase in one variable, decreases the other. If there is no dependency then we say that the variable are uncorrelated.

Variable x denotes the number of students trained on new projects, and variable y denotes the number of calls to the other institute.

We check the dependency of variable x on y. We see that some training increases the number of calls and some training decreases the number of calls

As there is no particular trend between training students and them getting call to the other institutions (neither increasing nor decreasing) so we cannot say whether it is a positive or negative correlation.

Thus this shows that there is no correlation between the variables.
