Quantitative Research Pt. 4 Flashcards
When is ANOVA used?
When looking for significant differences among 3 or more groups
Define one way anova
There’s just one independent variable, but the variable can have multiple different levels (i.e three different types of treatment)
Factorial ANOVA (How is it different from a one-way?)
More than one independent variable
Within subjects ANOVA (How is it different from a one-way?)
The same group is getting different i.v
• MANOVA (How is it different from ANOVA?)
Used when there’s more than one dependent variable and they are conceptually or statistically related
P values tell you the?
likelihood that your results occurred by chance
Define a type 1 error?
Saying there is a difference when there is not
Define a type 2 error?
Saying there’s not a difference when there is
What is the difference between statistical and clinical significance?
Clinical significance tells us: If the effect was large enough to make a difference?
How are effect sizes interpreted?
By seeing how much difference there is between the results of the experimental and control group?
Cohen’s d: Measures
effect size
Cohen’s d sizes
0.2 small, 0.5 medium, 0.8 large
What do confidence intervals tell you?
How close/accurate is the study’s estimate of effect?
Margin of error within your study
Range of values that likely includes the scores and responses of the population
__% confidence interval is often used.
95
What is the Belmont Report?
Outlines 3 major principles for doing research:
Autonomy- respecting people’s autonomy
Beneficence- The study should produce valid results so you’re not wasting people’s time and actually helping. Avoiding risks
Justice-Don’t exclude people, fairly distribute study to all possible members of sample
What is the Institutional Review Board (IRB)?
Independently reviews all proposals. It exists to: safeguard participant’s rights, ensure ethical standards in research,
What does the IRB do?
Judges the level of risk vs. benefit in your study
Name and describe the 3 ethical elements of human subject protections and the informed consent.
Full disclosure
Confidentiality
Voluntariness
What are the typical components of a grant proposal?
Statement of need, statement of benefit, statement of worthiness (why is your team the right team to do this study,) how are you going to implement it? What outcomes are you going to look at? Data analysis plan, timeline, personnel needed, evaluation, budget, letters of support, resume/cv
What are the 3 necessary characteristics of the grant budget?
Allowable- are the things you’re asking for money for allowable?
Allocable- Are the things you’re asking for money for actually connected to the study?
Reasonable- You haven’t overestimated your actual monetary needs.
True or False: Grant deadlines are flexible as long as you contact the program
coordinator.
FALSE
