Andre45 [30]

Answer:

The percentage of variation in the dependent variable explained by the variation in the independent variable is 80 %.

Step-by-step explanation:

A coefficient of correlation of 0.8 means that dependent variable changes in 0.8 when independent variable changes in a unit. Hence, the percentage of such variation ( $\%R$ ) is:

$\%R = \frac{\Delta y}{\Delta x}\times 100\,\%$

Where:

$\Delta x$ - Change in independent variable, dimensionless.

$\Delta y$ - Change in dependent variable, dimensionless.

If $\Delta x = 1.0$ and $\Delta y = 0.8$ , then:

$\%R = 80\,\%$

The percentage of variation in the dependent variable explained by the variation in the independent variable is 80 %.
