Question

question 8 of 10
an experiment can do what?

a. show how observation works

b. prove causation

c. show the hidden variable

d. illuminate the hidden variable

Explanation:

In scientific research (Natural Science, especially in experimental design), experiments are designed to control variables to establish cause - effect relationships. Option A: Observation is different from an experiment's main function. Option C and D: Hidden variables are more related to issues in correlational studies or statistical analysis, and experiments are not mainly for showing or illuminating hidden variables. Experiments, through manipulating independent variables and observing the effect on dependent variables while controlling other factors, can prove causation.

Answer:

B. Prove causation
