Psyc 302 final exam (actualexam)questions,answers 2024 – 2025
What is *Alternate-form* reliability? - ANSWERS-(temporal consistency or
stability, and inter-form consistency or equivalence)
— A measure of the extent to which 2 separate forms of the same test are
equivalent.
- example: form A scores should correlate with form B scores
What is *Split-half, odd-even (or random split)* reliability? - ANSWERS-(internal
consistency)
— The primary issue here is one of obtaining comparable halves.
- example: odd question scores should correlate with even question scores OR top
half should correlate with bottom half
{limitation = shortens the test in half [Spearman-Brown correlation fixes this] and
artificially lowers test score reliability}
,What is *Coefficient alpha (Cronbach's alpha)*? - ANSWERS-— This is a measure
of inter-item consistency (i.e., the consistency of responses to all items on the
test)
- an indication of whether each item on the test measures the same thing as every
other item on the test
What is *Scorer reliability or inter-rater reliability and agreement*? - ANSWERS-
the extent to which 2 or more raters are
consistent, or agree
- reliability = rank order
- agreement = magnitude (& rank order)
{limitation = raters could be bias}
What is *test and measurement validity*? - ANSWERS-the validity of a test's
scores concerns WHAT it measures and HOW WELL it does so
- it tells us what can be inferred from test scores
- validity depends on the USE of the test
- is the extent to which inferences drawn from the test scores are appropriate
What are the strategies for *assessing test score validity*? - ANSWERS-- criterion-
related
- content-related
- construct-related
- face validity
,What is the basic difference between true and quasi-experimental designs? -
ANSWERS-random assignment
A quasi-experimental design DOES NOT permit the researcher to control what? -
ANSWERS-the assignment of participants to conditions or groups
How are Quasi-experimental designs characterized? - ANSWERS-*lower levels of
control* over the WHO, WHAT, WHEN, WHERE, and HOW of the study
What is a nonequivalent control groups design? - ANSWERS-a research design
that has both experimental and control groups but the participants are NOT
randomly assigned to these groups
- most common type of Q design
What is the problem with nonequivalent control group designs? - ANSWERS-the
problem is knowing how to compare the results between groups when they are
not equivalent to begin with
What are Quasi-experimental designs? - ANSWERS-are research studies in which
participants are selected for *different* conditions from pre-existing groups and
self-selection into groups
Q designs are studies in which the IV are? - ANSWERS-selected from pre-existing
values and not created through manipulation by the researcher
, How are preexisting groups formed? - ANSWERS-by self-selected groups
ex. smokers vs nonsmokers
What is a central issue of quasi-experimental designs? - ANSWERS-research
validity
- interpretability depends on whether the pattern of results obtained can be
accounted for by possible differences between the groups or by something else in
the study
-- ceiling effects
-- floor effects
What is a ceiling effect? - ANSWERS-is the level at which an independent variable
no longer has an effect on a dependent variable, or the level above which
variance in an independent variable is no longer measured or estimated
- example: 2 profs teaching the same class, students in one class constantly was in
the 98% on exams > while the other class started at 20% then moved up to 98%.
One would not be able to deem the first prof as better because their teaching
methods may have had nothing to do with the student's high grades (could be
that they're just smart and would get those high grades no matter who the prof
was)
