Flashcards in Chapter 1 Definitions Deck (22):
The property that is measured in the research.
MEASURES THE EFFECT OF THE IV.
Variable other than the IV that could cause undesirable changes to the DV.
When potential effects of the EV have been removed.
Variable other than the IV that has a systematic effect on the DV.
RESEARCH IS A WASTE OF TIME IF IT IS PRESENT.
Using any person 'conveniently' available as part of the sample - are essentially biased and unreliable.
When the sample represent that population, so that the results/conclusions can be generalised to the wider population.
Sampling procedure in which each member of the population has an equal chance of being selected.
When the effects of a certain variable can be eliminated as a possible confound in an experiment.
When all participants in an experiment have an equal chance of being in the E/C-group.
Each participant is in the E/C-group.
Attempts to eliminate confounding variables by "matching" participants in E and C-group based on key characteristics.
Allocates participant to E/C-group randomly.
Type of confounding variable (Eg. Practice, fatigue, boredom etc.).
When participants' behavior is influenced by their expectations of how they should behave (caused by a placebo).
Participants don't know if they are in the E/C-group.
When the outcome of an experiment is unintentionally (or intentionally) affected by the experimenter.
No one knows who is in E/C-group.
Tell us about the "shape" of the data set.
NO CONCLUSIONS CAN BE DRAWN.
Statistical procedures that allow researchers to decide whether changes in the IV have cause changes in the value of the DV.
Probability that the difference in results is due to chance.
