B

Question 2

The name of the tool in SPSS Statistics that compares means and standard deviations among groups is:
A) Compare Means…
B) Descriptives…
C) Means…
D) Standard deviations…

Accepted Answer

C

Question 3

Assigning numerical codes to identify groups occurs in which column in the "Variable View"?
A) Label
B) Name
C) Values
D) Variable

Accepted Answer

Assigning numerical codes to identify groups occurs in the "Values" column in the "Variable View". This column allows you to create categories with associated numerical codes or value labels for your variable.

Question 4

The following variable defines groups:
A) Outcome
B) Dependent
C) Response
D) Independent

Accepted Answer

The term "independent variable" refers to the variable that is manipulated or changed by the researcher in order to observe its effect on the dependent variable. In this case, the variable that defines groups would be the independent variable, as it is the variable being manipulated. The other options listed (outcome, dependent, and response) all refer to the variable being observed or measured, rather than the variable being manipulated.

Question 5

The following variable defines participant changes:
A) Input
B) Dependent
C) Stimulus
D) Independent

Accepted Answer

Participant changes are the changes that are being measured or examined as a result of some kind of intervention or manipulation. As such, they are considered the dependent variable in a study.

Accepted Answer

The answer of In the Value Labels dialog box, click...

Question 7

The Means dialog box requires a Dependent variable and an Independent Variable to calculate means.

Accepted Answer

The Means dialog box in statistical software requires both a dependent variable and an independent variable to be selected in order to calculate means.

Question 8

Question 9

In the "Data View," each column is a new variable.

Accepted Answer

In the "Data View," each column represents a new variable, while each row represents a new observation or data point.

Question 10

To assign descriptive labels to numerical data, SPSS Statistics requires data values to be coded.

Accepted Answer

SPSS Statistics requires data values to be coded in order to assign descriptive labels to numerical data.
