Psychology ⇒ Research Methods in Psychology
Reliability and Validity starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Reliability and Validity.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A researcher develops a new intelligence test. To check if the test items are consistent with each other, which type of reliability should be assessed?
A researcher finds that their test scores are highly consistent over repeated administrations, but the test does not measure the intended construct. What does this indicate about the test's reliability and validity?
A researcher finds that two raters agree on 90% of their observations. What does this indicate about the study's reliability?
A researcher splits a test into two halves and finds a correlation of 0.85 between the two sets of scores. What does this indicate about the test's reliability?
A researcher wants to ensure that their experiment's results can be generalized to other populations. Which type of validity are they concerned with?
Describe how random error can affect the reliability of a psychological test.
Describe how you would assess the inter-rater reliability of an observational study.
Describe one method for improving the reliability of a psychological test.
Describe what is meant by inter-rater reliability.
Explain the concept of face validity and give an example.
Explain the difference between concurrent and predictive validity.
