An aerodynamicist, Dr. Sterling, is investigating the relationship between the angle of attack, θ\thetaθ (degrees), and the lift coefficient, CLC_LCL, of a prototype wing across 42 wind tunnel trials. After processing the experimental data, he calculates the product moment correlation coefficient (PMCC) to be −1.14-1.14−1.14.
Which of the following statements best describes this calculated result?
