PSYC 012 Chapter 9 Inquizitive UPDATED
Questions and CORRECT Answers
Fill in the blanks to complete the passage about the types of multivariate correlational studies.
- CORRECT ANSWER✔✔- A(n) [ longitudinal study ] is conducted over a longer period of
time than a typical correlational study to help establish [ temporal precedence ]. A(n) [
multiple-regression ] analysis considers more than two variables in the same analysis and can
help improve [ internal validity ].
Fill in the blanks to complete the passage about three types of correlations. - CORRECT
ANSWER✔✔- In a(n) [ cross-sectional correlation ], two variables measured at the same
time are associated. If an earlier measure of a variable is associated with a later measure of
the same variable, a(n) [ autocorrelation ] occurs. In a(n) [ cross-lag correlation ], an earlier
measure of one variable is associated with a later measure of a different variable. These three
types of correlations are usually found in [ longitudinal ] designs.
Fill in the blanks to complete the passage about variables that influence associations. -
CORRECT ANSWER✔✔- Additional variables may often add nuance or an alternative
explanation for a relationship. A [ moderator ] is a variable that explains how the two main
variables are related in different ways depending on the situation. A [ mediator ] explains why
two variables may be related based on an internal factor that connects them.
Fill in the blanks to complete the passage about multiple regression. - CORRECT
ANSWER✔✔- Multiple regression can help eliminate problems with [ internal validity ] by
controlling for potential third variables. It sets [ predictor ] variable(s) that influence the [
criterion ] variable, which is the outcome of interest. Effect sizes in multiple-regression
analyses can be represented by both [ beta ], which is a standardized effect size, and [ b ],
which is an unstandardized effect size.
Identify the true and false statements about pattern and parsimony. - CORRECT
ANSWER✔✔- True Statement(s):
The pattern and parsimony technique relies on the weight of the evidence from multiple
studies.
The pattern and parsimony technique exemplifies the theory-data cycle.
False Statement(s):
The pattern and parsimony technique works best when all of the studies surrounding a theory
use the same methodology.
, The pattern and parsimony technique can be considered only with experiments.
What type of approach do researchers use when they investigate causality with a variety of
correlational studies that all point in a single, causal direction? - CORRECT ANSWER✔✔-
pattern and parsimony
Jonide comes across a newspaper article with the headline, "Bigger Weddings Lead to
Happier Marriages." She reads that researchers recruited 418 married couples from a local
shopping center and collected their responses to a variety of survey questions, including some
asking about the number of guests at their wedding and their relationship happiness
(measured with questions about spousal satisfaction). This table presents the results of the
study.
Identify the validities that are reasonably established in this study. - CORRECT
ANSWER✔✔- Established:
statistical validity
construct validity
Not Established:
external validity
internal validity
Identify whether or not each psychological finding reported in the popular press represents
multiple regression. - CORRECT ANSWER✔✔- Multiple Regression:
"Facebook use predicted eating disorders in students only when adjusting for social
comparison behavior."
"Children in Head Start programs were found to be more successful than regular students
once researchers controlled for socioeconomic status."
Not Multiple Regression:
"Mediation was found to be helpful in treating substance abuse disorder in women but not in
men."
"Researchers found that age was indeed predictive of more conservative values."
João is investigating the relationship between body dissatisfaction as a predictor variable and
mental distress as the criterion variable. He suspects that self-esteem may mediate the
relationship between these two variables.
