Question

Shara collected two different data sets and labeled them data set S and data set T. Data set S has a correlation coefficient of −0.91, and data set T has a correlation coefficient of 0.89.Part A: Which data set has a stronger linear relationship?Part B: How do you know this?Select two answers, one for Part A and one for Part B.

Answer 1

Part A : 2nd Option

Part B : 5th Option

EXPLANATION :

From the problem, data set S has a correlation coefficient of -0.91, and data set T has a correlation coefficient of 0.89.

Note that the closer the correlation coefficient to 1 or -1, the stronger the linear relationship.

Since -0.91 is much closer to -1 than 0.89 to 1.

data set S has a stronger linear relationship

Because data set S has a correlation coefficient that is closer to 1 or -1
