Epidemiology Assignment Questions

This epidemiology assignment consists of three questions focusing on types of bias in research. Question 5 asks about selection bias, identifying validity as the relevant term. Question 6 addresses measurement bias, again linking it to validity. Finally, Question 7 requires students to identify potential biases in a survey about drug use among young people, considering response rate and selection bias.

Question 5
“Which of the following terms associated with selection bias? [2 points]”(a)
a) Chance.
b) Confounding.
c) Response rate
d) Validity
Answer: Validity. Specifically, external validity is associated with selection bias in that
selection bias brings about the systematic differences between the results of the control
group and the study group.
Question 6
“Which of the following term is associated with measurement bias? [2 points]”(c)
a) Effect Modification
b) Confounding.
c) Response rate
d) Validity
Answer: Validity. The fact that measurement bias instigates inaccuracy of results either from
overestimates or underestimates of results thus the validity of the research is at stake.
Question 7
"What biases would you suspect in a survey of the prevalence of drug use among young people
using a representative sample of students attending high school justify (not enough to name the
biases (No more than 60 words)" [4 points]

EPIDEMIOLOGY 3
The response rate may be low given the fear that the study population may have to admit to the
use of drugs and thus measurement bias. A selection bias will also be present given that the
researcher may incorporate more male youngsters into the study as compared to the female with
the thought that more male youngsters are affected.
