In a simple linear regression study between two variables x ( the independent variable) and y (the dependent variable), a random
large sample is collected and the coefficient of correlation r = −.98 is calculated. Which of the following conclusion may be made? Which is right choice. A) x and y are almost perfectly correlated, and y increases as x is increased.
B) x and y are moderately correlated, and y increases as x is increased.
C) x and y are almost perfectly correlated, and y decreases as x is increased.
D) x and y are very poorly correlated since r close to -1.
