Question

If two variables are positively linearly correlated, one of the variables tends to increase as the others __

Short answer

If two variables are positively linearly correlated, one of the variables tends to increase as the others increases .

Step-by-step solution

Basics 

p(rho) is a statistical parameter for the entire population, determining whether the variables are linearly correlated or not.

Linear correlation means variables change at a constant rate, and their relationship is denoted by straight line curve.

Explanation 

pindicates the magnitude of correlation in the variables' populations. It is between $+1$and $-1$.

If two variables are positively correlated, pis between $0$and$+1$

It means that two variables change in the same direction, one variable increase as other variable increase, and one variable decrease as other variable decrease.
