Quizplus · Accepted Answer

Time-sampling error refers to the variability in test scores that occurs when the same test is administered to the same group of people on different occasions. This type of error highlights how scores can change over time due to factors unrelated to what the test aims to measure, such as participants becoming more familiar with the test format or material.
