Any variable can be a correlation variable. In some cases there may be no apparent correlation but that, in itself, that means nothing. For example, the x and y coordinates in the equation of a circle (or any symmetric shape) are not correlated. On the other hand, there is a pretty good correlation between my age and the number of cars in the world.
A correlation variable is simply a variable that you study to see if changes in the variable that you are interested in is, in any way, related to changes in the correlation variable, and to get some idea of the degree to which they move in line.

What are the rules for a positive correlation?
As the explanatory variable increases, the response variable increases
Is a decrease in the independent variable and a decrease in the dependent variable a positive correlation?
yes
Why is correlation found?
Why Correlation?Because there is some relationship. One variable depends on another. Using correlation we can make inferences. Brahmajyothi
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
Which one of the following method serve to measure correlation bw two variable?
cofficient of rank correlation
When one variable decreases as a another increases what kind of correlation is that in psychology?
That is a negative correlation in psychology. It means that as one variable goes up, the other variable goes down.
What does it mean when two variables have a positive correlation?
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.
What is it called when one variable increases the other variable shows no relationship?
No correlation.
What does a correlation of-0.9 mean?
As one variable increases the other variable decreases.
What does a correlation of a -0.9 mean?
As one variable increases the other variable decreases.
What does a correlation of -0.9 mean?
As one variable increases the other variable decreases.
What are the rules for a positive correlation?
As the explanatory variable increases, the response variable increases
Is a decrease in the independent variable and a decrease in the dependent variable a positive correlation?
yes
What does a correlation of -0.9 mean?
As one variable increases the other variable decreases.
What does correlation of -0.9 mean?
As one variable increases the other variable decreases.

What does it mean for variables to show correlation?
A positive correlation coefficient means that as the value of one variable increases, the value of the other variable increases; as one decreases the other decreases. A negative correlation coefficient indicates that as one variable increases, the other decreases, and vice-versa.
