1.
The I.V. is the variable that is being measured by the experimenter.
2.
The D.V. is the variable that is being manipulated by the experimenter.
3.
List the steps for the complete research process.
A. 
B. 
C. 
D. 
E. 
F. 
Interpretation of results
G. 
H. 
Revise theory if necessary
4.
One tailed/directional hypothesis predicts an effect on the DV but does not say in which direction.
5.
Two tailed/non-directional hypothesis predicts an effect on the DV but doesn’t say in which direction. eg. Being bullied at school will affect exam performance.
6.
An experiment is where the experimenter manipulates the IV to see if it has an effect on the DV. It is the method of choice in psychology.
7.
Operationalisation: the attempt to define a variable in order to measure it effectively, defining what is meant by the variable.
8.
The experimental hypothesis predicts what the IV will be.
9.
Replication means an experiment must be set down in easy-to-follow steps so anyone can repeat the experiment with the same results.
10.
The Null hypothesis predicts no observable effect on the DV.
11.
Validity means that the results of an experiment match your hypothesis.
12.
The experimental group is the group carrying out the experiment in which the IV is present, e.g., smoking.
13.
Generalization is
A. 
Being sure that views can be applied to the whole population e.g. results from 10 people cannot be applied to whole population.
B. 
Making a general summary of an experiment.
C. 
Summing up the views of most psychologists.
D. 
14.
The experimenter effect is when characteristics of an experimenter affect the behavior of participants e.g., race, age, sex, general behavior, etc.
15.
Types of extraneous variables
A. 
B. 
C. 
D. 
Situational/environmental
E. 
16.
The three conditions of an experiment are:
A. 
Generalisation, replication, validity
B. 
Ethical adherence, controlled conditions, replication
C. 
Replication, accurate reporting, controlled conditions
D. 
17.
The Hawthorne effect refers to when participants feel [Blank] because they are participating in the experiment, and this [Blank] their behavior makes them try hard. George Elton Mayo, Western Electric Company, Illinois.
18.
Experimenter bias is when an experimenter is biased in his/her choice of participants.
19.
A Confounding variable is an extraneous variable that affects one or more conditions of the experiment but not all. As such, it DEFINITELY affects IV. Extraneous variables may not cause an effect.
20.
Random sampling refers to when all people in a target population have an equal chance of being selected for an experiment. Researcher may put all names in a hat, for example, or use a computer program to randomly select a certain number of names.
21.
Stratified random sampling is when the population is organized into groups based on social classification.
22.
Quota sampling is similar to Stratified Random Sampling, but the researcher will then pick participants from within each pre-identified sub-group.
23.
Demand characteristics refer to when searching for cues in an experimental environment to work out how to behave. They then behave in a [Blank] way because they think the experiment [Blank] this.
24.
Researcher has the whole population and then chooses a systematic method to select participants e.g., every tenth person on the list.
A. 
B. 
Stratified random sampling
C. 
D. 
E. 
F. 
Self-selected/volunteer sampling
25.
Quickest, cheapest, easiest. The researcher simply selects those that are willing and available e.g., stopping people in the street. This may result in the researcher being influenced by personality, looks, etc.
A. 
B. 
Self-selected/volunteer sampling
C. 
Stratified random sampling
