WORKBOOK EXERCISE 23
1. What is the r value for the relationship between Hamstring strength index 60°/s and the Shuttle run test? Is this r value significant? Provide a rationale for your answer.
ANSWER: The obligatory r value is -0.149 and this r value is not significant since the p-value for this correlation coefficient or r is 0.424 which is extra than 0.05 or 0.01 and henceforth at 5% and 10% both level , the null hypothesis of insignificance cannot be rejected and the assumption is the r value is not significant.
2. Consider r = 1.00 and r = −1.00. Which r value is stronger? Provide a rationale for your answer.
ANSWER: The r-values obligate alike seamless power. The positive r value displays a positive association among the variables, which suggest that one variable raises so does the other. The negative r value shows a negative connection, which propose that one variable increases the other decreases. The sign of r solitary signifies the direction of strength as here both r values are same without the sign so they are likewise strong.
3. Describe the direction of the relationship between the Hamstring strength index 60°/s and the Shuttle run test.
ANSWER: In this situation r value is negative. So as Hamstring strength index 60°/s upturns the Shuttle run test declines, and vice versa.
4. Without using numbers, describe the relationship between the Hamstring strength index 120°/s and the Triple hop index.
ANSWER: There subsists a reasonable positive connection among Hamstring strength index 120°/s and the Triple hop index. It means as Hamstring strength index 120°/s upturns, triple hop index increases. Similarly as Hamstring strength index 120°/s decreases, Triple hop index declines. Here the association is positive and it is significant at 5% significance level.
5. Which variable has the weakest relationship with the Quadriceps strength
