SFL 290 MIDTERM 2 VERIFIED STUDY GUIDE
test retest reliability - Answers - when the measure is given on two separate occasions,
is there consistency between the scores?
Parallel (Alternate) Form: reliability - Answers - consistency between forms of the test
Representative reliability - Answers - is the measure consistent across subpopulations
or groups of people?
Inter-Rater: Reliability - Answers - consistency from rater to rater
Internal (inter-item) Consistency: - Answers - consistency between individual items and
the total score
Ways to achieve reliability - Answers - Only ask about things respondent knows
Test-retest method
Split-half method
Use established measures
Prevent interviewer reliability problems
What are the statistical tests for reliability? - Answers - Test-retest=Correlation
coefficient,
Alternate form=Correlation coefficient,
Inter-rater=Cohen's kappa,
Inter-item=Cronbach's alpha.
Face Validity - Answers - The items on the scale appear to measure what people say
it's measuring. Is it telling us what we think it is?
Content Validity: - Answers - The full content of measure covered. Are all dimensions
covered?
Criterion Validity: - Answers - How does the measure relate to an already known
standard? Often assessed when you are developing a measure.
Concurrent (criterion Validity) - Answers - Do old scores on an already existing test and
new scores on a new created test match/correlate?
Predictive (criterion Validity) - Answers - Can your measure predict future performance
that is logically related?
