A teacher wants to assess the consistency of a 20-question math test. She divides the test into two equal halves, calculates the scores for each half separately, and then computes the split-half reliability. What does a split-half reliability coefficient of 0.90 indicate?a.The test is not reliable.b.The test is highly reliable.c.The test items are inconsistent.d.The test is moderately reliable.

In determining the consistency, two-halves of the same test are used.E.g. odd numbered items are group 1 and even numbered items in group 2. What type of reliability is it?a.Split-half methodb.Internal consistencyc.Test-retest reliabilityd.Parallel test method

To assess the reliability of a 120-question exam, an educator plans to use the Split-half method. How should this be done?Group of answer choicesThe questions in the first half of the exam should be compared to the second halfCronbach’s Alpha should be used instead of Split-halfThe educator should use an Alternate forms approachOdd and even numbered questions should be compared to each other

To assess the consistency of a measure from one time to another, when a same test is administered twice and the results of both administrations are similar, this constitutes the_______.Question 1Answera.Test- Retest Reliabilityb.Split-Half Reliabilityc.Internal Consistency Reliabilityd.Kuder-Richardson Reliability

_____________ is an estimate of reliability based on two half-tests

Two teachers are independently grading a set of essays for a writing competition. After comparing their scores, they calculate the inter-rater reliability coefficient, which is 0.35. What does this coefficient indicate?a.The teachers have a Low level of agreement in their scoring.b.The essays are too short for reliable scoring.c.The teachers have inconsistent grading standards.d.The participants have a low level of agreement in their scoring.
