Flashcards in 4.4 Experimental Method Deck (12):
The experimental method reduces ambiguity in the interpretation of results. With the experimental method, one variable is ____ and the other is then ____.
Another characteristic of the experimental method is that it attempts to eliminate the influence of all potential confounding third variables on the dependent variable. This is generally referred to as ____ of ____ variables.
control of extraneous
Any variable that cannot be held constant is controlled by making sure that the effects of the variable are ____.
Through randomisation, the influence of any extraneous variables is ____ in the experimental conditions.
With ____ ____, all extraneous variables are kept constant. If a variable is held constant, it cannot be responsible for the results of the experiment.
Experimental control is accomplished by treating participants in all groups in the experiment ____; the only difference between groups is the ____ variable.
identically, manipulated variable
The experiment method eliminates the influence of confounding variables by ____.
Randomisation ensures that the extraneous variable is just as likely to ____ one experimental group as it is to affect the other group.
To eliminate the influence of individual characteristics, the research assigns participants to the two groups and a ____ fashion.
This ability to ____ ____ research participants to the conditions in the experiment is an important difference between the experimental and non-experimental methods.
Direct experimental control and randomisation eliminate the ____ of any extraneous variables (keeping variables constant across conditions).
