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
