Provide a rationale for your answer. A negative correlation with r=-0.149. p=0.424>0.01 or 0.05, which is the given level of significance. 2. Consider r = 1.00 and r = −1.00. Which r value is stronger? Provide a rationale for your answer. The r-values have similar strength. The + r value show a positive relationship, which means when one value goes up so does the other. the - r value shows a negative relationship, showing that when one decreases the other would increase. 3.

Which variable has the weakest relationship with the Quadriceps strength index 120°/s? Provide a rationale for your answer. The shuttle run because it has the r value is less than all the others and the p value is greater than all the others. 6. Which of the following sets of variables has the strongest relationship? a. Hamstring strength index 120°/s and the Hop index b. Quadriceps strength index 60°/s and the Carioca test c. Quadriceps strength index 120°/s and the Side step test d. Quadriceps strength index 60°/s and the Triple hop index The answer is D. because r=0.619, which is closest to +1.00 than all the other answers. 7. In Table 5, two r values are reported as r = −0.498 and r = −0.528. Describe each r value in words, indicating which would be more
