Q

In a true experiment, the experimenter has complete control over the experiment. A quasi experiment is one in which the experimenter lacks some degree of control. The most important difference is that in a true experiment, the subjects are — to conditions, whereas in a quasi experiment, the subjects are — for conditions from —

A

assigned, selected, previously existing groups.

2
Q

The independent variables of an experiment are sometimes called —, each of which has at least — levels

A

factors, two

3
Q

In one-factor experiments, the levels of the variables are sometimes called – or —

A

treatments or conditions

4
Q

The two basic elements of good experimental design are:

A

1) the existence of a control group or a control condition
2) and the random allocation of subjects to various conditions

5
Q

Within-subjects control of order and sequence effects may be achieved by

A

randomization, block randomization, or reverse counterbalancing

6
Q

When it is not possible to control for order and sequence effects within subjects, the — technique may be used

A

Latin square

7
Q

The simplest possible true experiment has — conditions tested within subjects. All subjects experience both conditions in — order

A

two, counterbalanced

8
Q

— experiments are conducted when the hypothesis is not a simple yes or no question, when determining the shape of a function is desirable, or when multiple rival hypotheses must be ruled out.

A

Multiple-conditions

9
Q

Multiple-conditions,— experiments are common in perception research, as when one scales the brightness of different intensities of a light

A

within-subjects

10
Q

— design is used when a significant interaction between conditions would occur if tested –

A

A between-subjects, within subjects

11
Q

Some designs to avoid are the:

A

one-group posttest-only design,

the posttest-only design with nonequivalent control groups,

and the one group pretest-posttest design
