What is indicated by a positive value for a correlation?

We use correlation to measure how closely our input (x) increases and decreases with output (y) and vice-versa. The value of correlation is positive, if they are in sync, or increase together and fall together.

Answer: A positive correlation indicates that the two variables X and Y change in the same direction and sam magnitude.

A negative correlation is just the opposite of the normal correlation coefficient.

Explanation:

A positive value for a correlation indicates:

1. Correlation has a positive value.
2. There is an association or relation between the 2 variables, supposedly X and Y.
3. A little unit of change in variable X causes (may) impact in the Y variable, that is, if X moves higher then Y moves higher and if X moves to a lower value, then so does Y.
4. If the correlation coefficient is positive indicating a relationship between X and Y variables and the value lies between 0 to +1.

Cc value > 0.5 is considered a significant relationship between X and Y variables.

Cc = 0 indicates no significant relationship.

Thus, a positive correlation indicates that X and Y change in the same direction.
