Metod 2: 1.2 Flashcards
(31 cards)
In the independent groups design, the only factor that should differentiate the separate groups at the start of the experiment is the
independent variable
Which of the following terms describes the characteristic of an experiment that ensures an unambiguous interpretation for the outcome of the experiment?
internal validity
The cues and other information participants may use to guide their behavior in an experiment are called
demand characteristics
When a researcher is studying an individual difference variable, the levels of the independent variable are
selected
In a block in an independent groups design, each participant experiences
only one condition in the block
Relative to an independent groups design, a repeated measures design is generally ______ sensitive in its ability to detect an effect of the independent variable.
more
Which of the following statements best describes the characteristics of the complete repeated measures design?
Subjects are tested in each condition more than once
Which of the following is a balancing technique used in the incomplete repeated measures design?
ABBA counterbalancing
The systematic error variation due to individual differences among participants is _______ in the statistical analysis of repeated measures designs.
eliminated
The critical difference between a repeated measures design experiment and a longitudinal survey design is that
an independent variable is manipulated in the repeated measures design
A researcher compares students’ performance using a new learning strategy to their performance using the old strategy. Students’ performance is first tested with the old strategy, followed by the new strategy. The results indicate that students perform better with the new strategy. These results
are uninterpretable due to the confounding with practice effects
Which of the following occurs when the effect of one independent variable differs depending on the level of a second independent variable?
interaction effect
A researcher examines whether there are differences between musicians and non-musicians in their ability to remember simple and complex music passages. The design of this experiment is a
mixed natural groups design
In a 2 × 2 design with the independent variables, Presentation speed (Slow, Fast) and Type of task (Simple, Complex), which of the following would be one of the four conditions created using factorial combination?
slow speed/simple task
An interaction effect may be uninterpretable when this problem in measurement occurs:
ceiling or floor effect
Which term describes the characteristic of an experiment that ensures an unambiguous interpretation of the outcome?
internal validity.
When studying an individual difference variable, the levels of the independent variable are
selected.
Relative to an independent groups design, a repeated measures design is generally
more sensitive.
In a complete repeated measures design
subjects are tested in each condition more than once.
A balancing technique used in incomplete repeated measures designs is
ABBA counterbalancing.
Systematic error variation due to individual differences among participants is
eliminated.
The critical difference between a repeated measures experiment and a longitudinal survey design is
an independent variable is manipulated in the repeated measures design.
If performance improves from using the old strategy to the new one, these results
are uninterpretable due to the confounding with practice effects.
When the effect of one independent variable differs depending on the level of a second variable, it’s called
interaction effect.
