- Order and carryover effects are disadvantages of which design
- within subjects design
- Fewer people needed and yields more statistical power are advantages of which design
- within subjects design
- Yielding possible interaction effects is an advantage of what design
- factorial design
- A way to express factorial designs using numbers is known as
- shorthand notation
- When performance improves due to repeated testing this is due to?
- practice effects
- Another name for repeated measures?
- Within subjects design
- What attempts to control for order effects by varying the order in which subjects receive various treatments
- counterbalance
- Practice and fatigue are examples of
- order effects
- When performance declines due to repeated testing and not the IV, this is known as
- fatigue effect
- Which type experiment has the most control and generates the strongest cause and effect statements
- true experiment
- What type experiment is more popular but lacks random assignment
- quasi experiment
- Which type experiment has the poorest control
- pre-experiment
- What is considered a measure of stability
- test-retest
- What type reliability only gives a test one time
- inter-item
- Type of measure of internal consistency in terms of reliability
- split-half
- Shortening a test decreases it's reliability, what type reliability test shortens a test?
- inter-item
- Face and content are examples of what type validity
- subjective
- Predictive and concurrent are examples of which type validity
- criterion
- Another name for criterion validity
- objective
- Discriminant and convergent are examples of what type validity
- construct
- If we have a representative sample and a large sample what type validity do we have
- sampling validity
- True-experiment and random assignment are the reason we can make this statement that the test has good ___
- internal validity
- If something happens NOT due to chance we can say it is____
- statistically significant
- When using a representative sample and experimental realism we can establish this type validity
- external validity
- Another name for random sampling
- probability sampling technique or random selection
- Another name for proportional sample
- stratified random sample
- When using intact groups to get our sample we use?
- cluster random sample
- If we have to know how the population is proportional to do this sampling technique it would be what kind?
- stratified random sample
- Any clues available to the subjects that enable them to determine the purpose of the experiment are called
- demand characteristics
- A way to avoid having demand characteristics is to use a?
- cover story
- If we see a change in those being studied because they know they are being studied this is known as
- Hawthorne effect or reactivity
- Discriminant validity and convergent validity are methods of establishing this
- construct validity
- The use of alternate forms, test retest and inter item methods are ways to establish what
- test reliability
- A common way of establishing internal consistency is
- split half method
- If we use unobtrusive measures, we are trying to deal with this
- reactivity
- What is IRB?
- Institutional Review Board
- If eveyone has an equal chance of being place in any condition to make treatment groups as similar as possible, what is being done
- random assignment
- If the statistically significant level is set at .05 what is this level called
- alpha level
- This prevents experimenter bias and reactivity
- double blind
