Creating equivalence mean creating two groups that are the same in every possible
variable except for the manipulated IV. How do we create equivalence in
experimentation?
A person explains his opinion against buying a certain model of car by noting that
even though the model is popular and highly rated by numerous organizations, his
cousin has that model and has had a lot of problems. It is MOST accurate to state
that the person was
basing his opinion on anecdotal evidence
A researcher is investigating the effect of music on the productivity of employees in
a factory. Half of the employees listen to music while working and half do not listen
to music. The researcher measures the productivity of each employee. In this study
the employees who listen to music are the
experimental group
Random assignment
What needs to be the same for experimental and control groups?
Whatever isn't being studied. Everything except the IV.
A manipulation check allows us to be sure that we have successfully...
created conditions in which the amount of the conceptual IV differs
A disadvantage or limitation of the experimental research method is...
it frequently takes place under artificial circumstances.
After designing a study to investigate the role of gender on learned helplessness a
clinical psychologist collects data from 100 participants. What is the clinical
psychologist's next step in the investigation?
Analyze data and draw conclusions

,If two variables have a negative correlation, you would expect that _____ scores on
one variable are generally associated with ____ scores on the second variable.
low; high (or vice versa)
The scientific approach requires that people specify exactly what they are talking
about when they formulate hypotheses. Which advantage of scientific investigation
does this illustrate?
precision
Which of the following are disadvantages of the experimental research method?
a) it cannot be used to explore all research questions
b) it can produce artificial situations that may not be applicable to real life
c) it is impossible to manipulate certain variables
d) all of the above
d) all of the above
Which of the following is NOT a criticism of using animals in psychological
research?
a) many of the studies are trivial
b) it is unethical to subject an animal to pain
c) the studies cost too much for the limited amount of information they provide
d) the studies are a waste of time, as the results often do not apply to humans
c) the studies cost too much for the limited amount of information they provide
A correlation coefficient of zero describes
the lack of a relationship between two variables
A researcher is investigating the effect of high room temperature on aggressive
behavior in preschoolers. Half of the children are in a classroom where the
temperature is a warm 88 degrees and half are in a classroom where the temperature
2
, is a normal 77 degrees. The researcher measures the number of hitting incidents that
occur in each classroom. In this study the children in the warm classroom are the...
experimental group
Which of the following is an example of an independent variable that can be
manipulated?
a) number of correct responses
b) amount of exposure to caffeine
c) subject age
d) subject gender
b) amount of exposure to caffeine
Which of the following is NOT one of the three goals of science?
a) application and control
b) measurement and description
c) construction and revision
d) understanding and prediction
c) construction and revision
A group of researchers wanted to determine if people will eat more food in a room
with red paint and red decorations than in a room that is decorated blue. Half the
participants in this study ate in a red room and half ate in a blue room. The
researchers then measured how much food was consumed in each of the two rooms.
In this study, the independent variable was
the color of the decorations in the room
The experimental method is a research method in which the investigator manipulates
a variable under carefully controlled conditions and then
observes whether any changes occur in a second variable as a result
