CSD 5318 Final Exam – graduate-level study guide and exam preparation
material
If I were comparing the mean scores for two treatments given to the same subjects, I might
use: - correct answer ✔✔within subjects, repeated measures t-test
Correlation studies are useful in that they provide an estimate of: - correct answer ✔✔Strength
of relationship
If I have a Pearson r-value of -0.8, this indicates: - correct answer ✔✔a strong negative
relationship
R2 can be interpreted as estimating the proportion of: - correct answer ✔✔how much of the
variability in one variable can be explained by it's relationship with the other variable
Fitting a line to a set of observations via linear regression allows you to: - correct answer ✔✔1.
Make the relationship b/w variables easier to see.
2. Provides a summary of the relationship.
3. Allows prediction.
Experimental power refers to: - correct answer ✔✔Probability of rejecting a false null
hypothesis (Type II error), ability to find real effect.
If I am really excited about my study results and want to mention, in the paper I'm writing,
the potential ways in which they could have a large impact on patient care, this would be
appropriate: - correct answer ✔✔in the discussion section.
If I needed to compare more than two groups, I might use: - correct answer ✔✔ANOVA
, In an ANOVA, an F value more extreme than the relevant critical value tells you that ____. -
correct answer ✔✔atleast one pair is different.
If I had done lots of statistical tests in a study, I might need to adjust my significance
thresholds via _______ methods, such as ______. - correct answer ✔✔multiple comparison
correction ; bonferroni
If I wanted to know more than whether a hypothesis test was significant or not, and needed
to know something about the magnitude of the finding, I would need to measure: - correct
answer ✔✔Effect Size
Chi-squared measures category association by comparing ____ and _____. - correct answer
✔✔observed frequency; expected frequency
There are three types of clinical data collection that we discussed: 1) ____, which measures
____, 2) ____ which measures ____, and 3) ____ which measures ____. - correct answer ✔✔1.
Treatment- immediate outcomes
2. Generalization Probe- things that are likely to change
3. Control Probe- things that are not expected to change
Barriers to evidence-based practice include: - correct answer ✔✔Role of qualitative research,
time constraints, lack of treatment outcomes research, hierarchies of evidence.
There are several types of review papers - two common ones include: ____, which focus on
____, and _____ which focus on _____. - correct answer ✔✔1. Narrative: Promotes 1 Stance
2. Systematic: Neutral
