Chapter 9 Flashcards
T/F
The design of research is the experiment’s specific content
False. it is only the structure of the experiment
In between subject design, how many conditions do subjects participate in?
One
T/F
The representativeness of our sample determines whether we can generalize our results to the entire population from which the sample was drawn.
True
It increases the experiment’s external validity
Random sampling
It is is a statistical estimate of the size or magnitude of a treatment effect.
Effect size
T/F
The smaller the effect size, the stronger the relationship between the independent and dependent variables, and the fewer subjects needed to detect a treatment effect.
False. The larger the effect size
How many subjects in each treatment should you have to detect a strong treatment effect?
at least 10-20 subjects
T/F
in two independent groups design, you compare two independent variables
False. Levels Independent Variables
This compare the effect of different values of the independent variable.
Experimental group-control group design
T/F
The experimental group receives a level of the IV and the control group receives the same procedures, but receives one treatment.
False. no treatment
T/F
In a two experimental groups design, we assign subjects to one of two levels of the independent variable.
True
T/F
Random assignment works well even with 5-10 subjects per condition.
False.
It is a between-subjects design with more than two levels of an independent variable.
Multiple groups design
It is a trial run of the experiment that uses a few subjects.
Pilot study
T/F
A pilot study can’t help the experimenter refine the procedure or determine whether the experiment is
promising. It can only define the relationship between variable.
False. A pilot study can help the experimenter refine the
procedure or determine whether the experiment is
promising.
