Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85. Which could be concluded based on the correlation coefficient of the data?

A. There is a strong relationship showing that as the number of days increases, the height of the plants increases.
B. There is a strong relationship showing that as the number of days Increases, the height of the plants decreases.
С. There is a weak relationship showing that as the number of days increases, the height of the plants increases,
D. There is a weak relationship showing that as the number of days increases, the height of the plants decreases,

Because the correlation coefficient of 0.85 is very close to 1, there's going to be a strong, positive linear correlation between the two variables. Therefore, option A is correct.

There is a strong relationship showing that as the number of days increases, the height of the plants increases.

What is the correlation coefficient of the data?

A correlation coefficient is a bivariate statistic when it summarizes the relationship between two variables, and it’s a multivariate statistic when you have more than two variables.

Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85.

When the correlation coefficient is above 0.8, the correlation cofficeint is strong.

And the function is increasing.

So, there is a strong relationship showing that as the number of days increases, the height of the plants increases.

Hence, there is a strong relationship showing that as the number of days increases, the height of the plants increases.
