Step 1
Which of the following best describes the findings of this test?
Answer
To analyze the findings of the test, we need to assess both validity and reliability.
-
Validity: The test measures what it intends to measure, which is the speed of the athletes during a 100-metre sprint. The setup ensures that conditions are the same for all athletes, making it a valid measure of their sprinting speed.
-
Reliability: Although the test is valid, it relies on a single attempt for each athlete. If an athlete has an unusually good or bad day, it may not accurately represent their usual performance. Therefore, while the method is sound, the reliance on just one run per athlete means the test is not highly reliable.
Based on this analysis, the most accurate description of the findings of this test is: A. Valid but not reliable.
