Use distributive property: a(b + c) = ab + ac
x(2x + 3) = (x)(2x) + (x)(3) = 2x² + 3x
The correlation coefficient is defined as the degree of <u>linearity</u> between two <u>quantitative</u><u> </u> variables.
<h3>What is Correlation Coefficient</h3>
Th association between two quantitative variables is measured by the correlation coefficient.
Thus, correlation coefficient, r, which ranges from 1 to -1, it shows the strength of linear association between two random variables that are normally distributed.
In summary, the correlation coefficient is defined as the degree of <u>linearity</u> between two <u>quantitative</u><u> </u> variables.
