Question

An epidemiologic experiment is performed in which one group is exposed to a suspected factor and the other is not. All individuals with an odd hospital admission number are assigned to the second group. The main purpose of this procedure is to:a. ensure a double-blind study.b. prevent observer bias with respect to the factor.c. prevent observer bias with respect to the outcome.d. improve the likelihood that the two groups will be comparable with regard to known and unknown confounding factors.e. guarantee comparability of the two groups with regard to other relevant factors.

Answer 1

d. improve the likelihood that the two groups will be comparable with regard to known and unknown confounding factors.

Step-by-step explanation:

Epidemiology is the term that is used to define a study in which the study is done on a defined population for the health related issues, that is about answering the who, when and where related to this study.

In this given question also the experiment focuses on developing two different groups to understand and conduct the study and analysis properly, based on the suspected factor and how they react to it.

Thus, it will lead to compare the groups in order to make the analysis efficient keeping constant factors.
