The experimental method reduces ambiguity in the interpretation of results. With the experimental method, one variable is ____ and the other is then ____.

manipulated, measured

1

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

2

Any variable that cannot be held constant is controlled by making sure that the effects of the variable are ____.

random

3

Through randomisation, the influence of any extraneous variables is ____ in the experimental conditions.

equal

4

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

5

Experimental control is accomplished by treating participants in all groups in the experiment ____; the only difference between groups is the ____ variable.

identically, manipulated variable

6

The experiment method eliminates the influence of confounding variables by ____.

randomisation

7

Randomisation ensures that the extraneous variable is just as likely to ____ one experimental group as it is to affect the other group.

affect

8

To eliminate the influence of individual characteristics, the research assigns participants to the two groups and a ____ fashion.

random

9

This ability to ____ ____ research participants to the conditions in the experiment is an important difference between the experimental and non-experimental methods.

randomly assign

10

Direct experimental control and randomisation eliminate the ____ of any extraneous variables (keeping variables constant across conditions).

influence

11
