Rancesca has devised a 20-question survey to measure parenting style. She wants to demonstrate the reliability of this new measure. a) Which kind(s) of reliability (test-retest, split-half, or inter-rater) would you suggest she attempt to demonstrate? b) Explain why you chose the type(s) of reliability you did and why you didn’t choose the other type(s) of reliability.

The reliability she should demonstrate is the test-retest reliability. Because it will help her to determine the accuracy of the answers parents provided in the survey.

Explanation: Test-retest reliability is the a type of reliability that is used to determine the accuracy of a score. This is done by given a question to students to answer, and given them the same question again after a period of time.

For Rancesca to determine the reliability of her result from a survey questions, she should give the same survey questions to the same group of people to answer again, after a period of time.

This will help her know if what each parents has answered according to their Behavior. Because a parents that answers according it's behaviour is likely to provide the same answer.

Split-half reliability

Explanation:

I would prefer not to use inter rater to demonstrate the reliability of this new measure because this would be dependent on the people observing BUT would rather use SPLIT HALF RELIABILITY because it would show consistency within the measures and test retest for showing the same product over time which will in turn make the reliability of the new measure when demonstrated with split half to be accurate, effective and efficient.
