A physical therapist collects data on the flexibility of patients' hamstrings using a sit-and-reach test. The data collected has a high degree of variability. Which of the following measures of variation would be most appropriate to report to describe how spread out the data is?
A) Mean
B) Mode
C) Range
D) Median
Answer: C) Range
Rationale: The range is a measure of variation that describes the difference between the highest and lowest scores in a data set. It is commonly used to indicate the spread or variability of the data. Although other measures such as the mean or median describe central tendency, the range is best for understanding the extent of variability in the data. The standard deviation would also be appropriate, but the range is the most basic measure.

A researcher is conducting a study to compare the effectiveness of two different rehabilitation techniques for improving shoulder mobility in patients post-rotator cuff surgery. The study utilizes a crossover design, where participants receive both treatments in a random order, with a washout period between the two interventions. What is a primary advantage of using a crossover design in this type of study?
A) It allows for a larger sample size due to the use of multiple groups.
B) It minimizes variability by having participants serve as their own control, which improves the reliability of results.
C) It is more time-efficient than parallel group designs because only one intervention is used at a time.
D) It eliminates the need for a washout period between interventions.
Answer: B) It minimizes variability by having participants serve as their own control, which improves the reliability of results.
Rationale: A crossover design is beneficial because each participant receives both interventions in a randomized order, allowing them to serve as their own control. This helps to reduce variability between groups, making the results more reliable. A washout period is essential to ensure that the effects of the first intervention do not carry over into the second intervention phase.
A physical therapist is conducting a study to evaluate whether a new exercise program improves patient mobility more than the standard program. The therapist hypothesizes that the new program will result in better mobility scores than the standard program, but does not expect it to result in worse scores. Which type of hypothesis test would be most appropriate for this study?
A) Two-tailed test
B) One-tailed test
C) Paired t-test
D) Chi-square test
Answer: B) One-tailed test
Rationale: A one-tailed test is appropriate when the research hypothesis specifies the direction of the expected effect, as in this case, where the therapist predicts that the new program will improve mobility scores (but not worsen them). A two-tailed test would be used if the researcher were testing for a difference in either direction (i.e., improvement or deterioration).
