Quiz 2 Flashcards
A concise definition of the target population is important in determining:
Group of answer choices
Precision of measurements
Internal validity
The patients to whom you can generalize the results of the study
The power of the study
The patients to whom you can generalize the results of the study
A good operational definition of the independent variable will include:
Enough details about the procedures that someone else could replicate them.
Internal validity
A description of the tools used to measure the treatment
All components of the result study
Inclusion and exclusion criteria
Enough details about the procedures that someone else could replicate them.
Which of the following operationally defines your target population?
Inclusion criteria
Inclusion and exclusion criteria
Measurement processes
Exclusion criteria
Parameters of the intervention
Inclusion and exclusion criteria

In this study, what would be your independent variable?
Intervention group
Patient Satisfaction
Hearing aid device
Hearing retraining program
None of the answers provided
intervention group
You are interested in determining if a hearing retraining program results in better patient satisfaction than a hearing aid device in patients with tinnitus.
In this study, how would you operationally define your dependent variable?
One group pretest-posttest design
Explain how you intend to measure patient satisfaction
Describe your inclusion and exclusion criteria
Identify potential confounding factors
Provide a detailed description of the hearing retraining program and the hearing aid device
Explain how you intend to measure patient satisfaction
The notion of generalizability refers to:
Interval validity of a study
Results of a pilot study
The scope of your purpose statement
The statistical tests you choose
The degree to which results from a study can be applied to the entire target population
The degree to which results from a study can be applied to the entire target populationf
I am proposing to test this hypothesis: Vestibular rehabilitation will significantly improve dizziness, as measured by the Dizziness Handicap Index, better than a rest-only protocol.
What component is missing from my hypothesis statement?
Independent variable
Target population
Dependent variable
Statistical test

In outlining the research question for my report of a study comparing the efficacy of a balance program to a placebo (doing nothing) to prevent falls, I refer to my independent variable as “balance program.”
What is the problem?
I haven’t defined efficacy
I haven’t defined the target population
I haven’t operationalized my dependent variable
I have selected a constant, rather than a variable
I have selected a constant, rather than a variable
Which of the following is an educated guess about the results of the study?
