In one study it was found that the correlation coefficient between two variables is 1.0 which statement is true

       

Step-by-step explanation:

We are given the following information in the question:

Correlation between two coefficients is 1 between two variables.

Correlation:

Correlation is a technique that help us to find or define a relationship between two variables. It is a measure of linear relationship between two quantities. A positive correlation means that an increase in one quantity leads to an increase in another quantity A negative correlation means with increase in one quantity the other quantity decreases. +1 tells about a a perfect positive linear relationship.

So, if two variables have a correlation coefficient of 1 the, if one quantity increase then we can see equal increase in the second quantity.
