#6
What is a confounding variable in experimental research?

#7
Which of the following best describes the purpose of meta-analysis in health psychology research?
To combine results from multiple studies to increase statistical power
To analyze data collected from a single study

#8
What is the difference between internal validity and external validity in research?
Internal validity refers to the generalizability of findings, while external validity refers to the accuracy of measurement
Internal validity refers to the accuracy of measurement, while external validity refers to the extent to which findings can be generalized
Internal validity refers to the extent to which the study design eliminates confounding variables, while external validity refers to the extent to which findings can be generalized
Internal validity refers to the accuracy of measurement, while external validity refers to the extent to which the study design eliminates confounding variables
#9

A study following a group of individuals over several years to assess changes in mental health
A study analyzing survey responses from a large sample of participants
#10
What does 'p-value' represent in hypothesis testing?
Probability of making a Type I error

Probability of obtaining the observed results by chance
Probability of rejecting the null hypothesis
#11
In health psychology research, what is meant by the term 'effect size'?
The probability of obtaining a significant result
The size of the difference between groups
The strength of the relationship between variables
The likelihood of replicating the study's findings
#12
What is the purpose of random assignment in experimental research?
To ensure that the experimental group and control group are equivalent
To eliminate the influence of extraneous variables
To manipulate the independent variable
To determine the direction of causality
#13
What statistical test is appropriate for examining the relationship between two continuous variables in health psychology research?
Chi-square test
Independent samples t-test
Pearson correlation
ANOVA
#14
In health psychology research, what is the purpose of a pilot study?
To test the feasibility of the research design and procedures
To gather preliminary data for hypothesis testing
To analyze the statistical power of the study
To recruit participants for the main study
#15
Which of the following best describes a quasi-experimental design?
A design that randomly assigns participants to different groups
A design that lacks a control group
A design that manipulates the independent variable but does not control extraneous variables
A design that cannot establish cause and effect relationships
#16
In health psychology research, what does 'qualitative data' refer to?
Data collected using closed-ended questions
Data that can be quantified
Data that consists of words, descriptions, and images
Data that is analyzed using statistical tests
