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

There is only one statement

Step-by-step explanation:

Step-by-step explanation:

We are given the following information in the question:

Correlation between two coefficients is 1 between two variables.

Correlation:

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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
