Surver research Flashcards
Name all types of reliability
Test-retest
alternate form reliability
internal consitency
inter-observer
Test-retest reliability
Ask the same respondents to complete the
survey questions at different times.
If the correlation, , between the first set of
answers and the second is greater than 0.7,
we can assume that test-retest reliability is
good.
alternate form reliability
Test-retest reliability
suffers from practice
effect and recall
problems.
Solution: Give the same
respondents different
versions of the
questionnaire with
questions being
reworded or reordered.
internal conscistency reliability
Ask group of questions that measure
different aspects of the same concept.
We want to make sure that these aspects
are consistent with respect to the overall
concept.
Inter-observer (inter-rater) reliability:
We need to check whether or not different
observers give similar answers when they
assess the same situation.

name all types of validity
content validity
criterion validity
construct validity
content validity
Subjective assessment of how appropriate
the instruments seems to a group of
reviewers with knowledge of the subject
matter.
criterion validity
Compares one instrument to another
instrument.
construct validity
Assess the extent to which different data
collection approaches produce similar
results.
Often requires many years of experience to
assess it.
