302 FINAL EXAM 2026 Edition Actual Questions And Correct
Detailed Answers
Quasi (case control)-CORRECT ANSWER-Level 3 Experimental design
- Intervention group-Testing a mindfulness intervention in
pregnant women who smoke
- Due to ethical considerations-you cannot randomize and make
people don't smoke or smoke
- Still have intervention-But no randomization
7 Most Frequently Used True Experimental Designs or RCTs-
CORRECT ANSWER-·Two-group RCT with pretest/posttest design
·Two-group RCT with posttest-only design
·Two-group RCT with repeated measures
·Two-group RCT with control group receiving no intervention
·Three-group RCT
·Solomon four-group design (strength: isolate bias)

·Factorial design.(Why would I choose this design? What am I looking
for?)
look at pictures on week 9 slides for characteristics of RCTs-CORRECT
ANSWER-im going to look now
Know threats to internal validity (was the study carried out well?) -
CORRECT ANSWER-- History: Results that occur from an event or
organizational intervention unrelated to the study intervention (e.g.
Cdiff outbreak and handwashing practice)
Maturation:ResuIts occurring from developmental change that
occurs independent of the study treatment; usually occurs gradually
(e.g.speech development)
Repeating testing/practice effects: Results occurring from
practice with testing or repeated exposure to the same measurement
instruments
Attrition: Most often encountered in repeated measure
testing, effect could be due to dropout of sickness or least
interested/motivated

Know attrition and how to calculate and consider attrition rate when
determining sample size-CORRECT ANSWER--Attrition:Most often
encountered in repeated measure testing, effect could be due to dropout
of sickness or least interested/motivated
200 people in the study with 10% attrition rate. How many people
should include in the study?
200+20=220
why does attrition happen-CORRECT ANSWER--Personal
circumstances
-Lose of interest
-Time constraints
- Dissatisfaction with study protocol
-Adverse effects
why consider attrition-CORRECT ANSWER--Can introduce bias if the
characteristics of participants who drop out differ from those who
continue to participate

- Attrition leads to missing data which can reduce the statistical power of
the study and affect the precision of the estimate.
-Missing data can introduce challenges in data analysis and interpretation,
as well as limit the ability to draw conclusion Why do a pilot study?-
CORRECT ANSWER-Pilot studies allow revision of the intervention if
needed and allow demonstration of study
FEASIBLITY.
quasi experimental-CORRECT ANSWER--do not randomize
- participants can self select
- may not have control group
-manipulate variables
- money
-ethics
-level 3
case control-CORRECT ANSWER--non-experimental
-retrospective
-predictor variable for disease
- cases have condition
