Correct option is D
When a golfer consistently hits the ball into the hole on every shot:
1. High Validity:
· The intended goal (hitting the ball into the hole) is consistently achieved, indicating the measure or performance is accurate and aligns with the desired outcome.
2. High Reliability:
· The consistency of performance (the golfer hitting the ball into the hole on every attempt) shows a high level of reliability.
This combination of accurately achieving the intended result and doing so consistently reflects both high validity and high reliability.
Explanation of Other Options: · (a) No validity and No reliability:
· If the golfer misses the hole frequently and the results are inconsistent, this would indicate neither validity nor reliability.
· (b) Low validity and Low reliability:
· Inconsistent results with outcomes far from the target would reflect low validity and low reliability.
· (c) Low validity and High reliability:
· If the golfer consistently misses the hole but hits the ball in the same direction each time, the performance would lack validity but show reliability.
Correct Answer:
(d) High validity and High reliability
Information Booster 1. Validity and Reliability:
· Validity: Measures whether the performance accurately achieves the intended outcome.
· Reliability: Measures the consistency of performance or results over repeated attempts.
2. Examples in Sports:
· High Validity and High Reliability: A basketball player consistently making free throws.
· Low Validity but High Reliability: A shooter consistently missing the target but hitting the same wrong spot.
3. Applications in Testing:
· Ensuring both validity and reliability is critical in assessments, research, and skill evaluations.
