Reliability refers to the extent to which result are ________________

• Consistent

• Inconsistent

• Correct

• Incorrect

____________ reliability refers to assessing the consistency of participants data when they complete the research on more than one occassion.

• Test-retest

• Face

• Interobserver

• Interscorer

Inter-scorer reliability is how often different scorers agree with each other on the same cases.

• False

• True

What is an example of inter-scorer reliability?

• A bank manager wants to assess customer satisfaction.

• Such as Olympics ice skating or a dog show

• if students get similar scores on the test regardless of the day when they take it.

Test-retest method is...

• A method to get two set of scores of the same test to compare.

• A method to make students retake a test to finally pass the exam.

• A method to ensure the test is valid enough and can be applied.

• A method to make sure not many students fail a course.

In the split half method...

• The students take one half of the test one day, the other half another day and then are marked and marks are compared to measure reliability.

• The class group is divided in two and they take two different versions of the same test.

• Students decide what half of the test to do and are scored on it. Then results are compared to measure reliability.

• Subjects take the test in the usual way, but each subject is given two scores, one for each half of the exam. The two scores are compared.

Validity is a concept that... (choose the best answer)

• Measures the consistency of the measurement taken under the study.

• Measures the accuracy of the concept that it supposes to measure.

• Covers the full range of the issue set for the study

It is important for the teacher to understand the concept of validity because:

• Teachers should consider more than one learning objective across other subjects when assessing students.

• It does not matter because they do not create any assessments.

• Teachers must understand that any created assessment should accurately measure what it is intended to measure.

What answer best describes the difference between validity and reliability?

• If an assessment is reliable, your results will be very similar no matter when you take the test. Assessment validity refers to how well a test measures what it is supposed to measure.

• Reliability stands refers to being able to count on a test score while validity stands for an assessment being valid.

• Reliability refers to an assessment being simple while validity refers to a complex assessment.
