Assignment:
1. What is the r value for the relationship between Hamstring strength index 60% and the shuttle run test? Is this r value significant? Provide rationale.
2. Consider r=1.00 and r=-1.00. Which r value is stronger? Provide rationale
3. Describe the direction of the relationship between the Hamstring strength index 60% and the shuttle run test.
4. Without using numbers, describe the relationship between the Hamstring strength index 120% and the Triple hop index.
5. Which variable has the weakest relationship with the Quadriceps strength index 120s? Provide rationale.
6. Which of the following sets of variables has the strongest relationship?
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 statistically significant, provide a rationale
The researchers stated that the study showed a positive, significant correlation between Quadriceps strength indicts that pre and postoperative functional stability. Considering the data presented in table 5, do you agree with their statement? Provide rationale
7. The researchers stated that no significant relationship could be described between Hamstring strength indicates 60s and functional stability. Give the data in table 5, explain why not.
8. Consider the relationship reported for the Quadriceps strength index 120s and the Hop index (r=0.744**, p=0.000) What do these r and p values indicate related to statistical significance and clinical importance?
1. What is the r value listed for the relationship between variables 4 and 9? Describe the correlation r=0.32** using words. Is this a statistically significant correlation? Provide a rationale .Calculate the percentage of variance explained for r=0.53. Is the correlation clinically important? Provide rationale
2. According to table 2, r=0.15 is listed as the correlation between which two items? Describe the relationship. What is the effect size for this relationship, and what size sample would be needed to detect this relationship in future studies?
3. Calculate the percentage of variance explained for r=0.15. Describe the importance of this relationship.
Which two variables in Table 2, have the weakest correlation, or r value? Which relationship is the closest to this r value? Provide rationale
Is the correlation between LOT-R total scores and avoidance-distraction coping style statistically significant? Is the relationship relevant to practice? Provide rationale
4. Is the correlation between variables 9 and 4 significant? Is this correlation relevant to practice? Provide rationale.
5. Consider two values, r=0.08 and r=-0.58. Describe them in relationship to each other. Describe the clinical importance of both r values.
Examine the Pearson r value for LOT-R total, which measured optimism with the task and emotion coping styles. What do these results indicate? How might you use this information in your practice.
