Question

A medical researcher hypothesizes that a new drug can reduce cholesterol. Which of these would most likely be the dependent variable in a study involving this medication?

A. The number of participants in the study.
B. The ages of the people treated for cholesterol with other medications.
C. The cholesterol level of the participants in the study.
D. The number of people treated for high cholesterol with other medications.
which is it?

Answer 1

C. The cholesterol level of the participants in the study.

Step-by-step explanation:

The dependent variable is the one that is being studied in the experiment. In the given experiment, the effect of the drug on cholesterol levels is being studied.

Hence, the cholesterol levels of the experimental group would serve as a dependent variable here. According to the hypothesis, the cholesterol level is supposed to be reduced in the experimental group that is being treated with the drug.

Answer 2

The answer is "C. The cholesterol level of the participants in the study".

In a test or any experiment, the independent variable is controlled and the impacts watched. These watched impacts or observed factors are known as dependent variables. They are frequently the conjectured result of controlling the independent variables.
A change in the dependent variable relies upon the independent variable and it's this relationship that scientists endeavor to measure when directing tests.
