Research methods exam 1
Which of the following statements is true of a theory?
It is used to organize and explain specific facts
Which of the following best describes a mixed factorial design?
It uses both a between and within-subject design
Which section includes a description of exactly how the study was designed and conducted?
Method
The graph is simply a flat line when there is ________ between two variables
No correlation
Which is a problem with making casual statements when the non experimental method is used
determining the direction of cause and effect
If the hypothesis is not supported, the author should suggest potential reasons in the
discussion
How can you reduce the experiment bias?
have a double-blind experiment
In a factorial design, a main effect is the effect each _____ variable has by itself.
independent
When describing relationships between variables, a correlation nearer to 1.00 (plus or minus)
indicates the relationship between variables is strong
Developing a broad theory AFTER thinking about a specific experience is an example of
induction
Taking an experiment out of the lab and conducting it in real social situations could decrease
internal validity
The more time individuals spend in a department store, the more purchases they tend to make
it depends on whether the amount of time was manipulated
A factorial design involves
more than one independent variable
The lower the price of hamburgers, the more hamburgers sold
negative correlation
Which of the following is the general format for describing factorial design?
number of levels of 1st IV x number of levels of 2nd IV
An IV x SV design has at least
one manipulated and one subject variable
Increases in the values of 1 variable are accompanied by increase in 2nd variable
postive correlation
Where would you find the tables and graphs in an empirical article?
results
What is Not included in the discussion section?
results of the experiment
What is NOT included in the introduction
summary of results
When describing relationships between variables, a correlation of 0.00 indicates that
there is no relationship between the variables
Factorial designs are often employed because
they give a greater approximation of real-world conditions
Experiment tests effect of temperature (C, W, H) noise level (Q, L), and room color (P, B, R)
this design tests 3 main effects
The simplest factorial design is the one that has
two independent variables with two levels each
Increase in 1 variable are accompanied by systematic increases and decreases in a 2nd variable
curvilinear relationship
A study of the effects of lighting (low, M, High) and temperature (cold, warm, hot) on joy
1 interaction is possible
A 4x5 factorial design would have _______ conditions.
20
A numerical index of the strength of relationship between variables in called a _______ coefficient
Correlation
Random variability exists because relationships between variables
are rarely perfect
What is NOT included in the abstract
