Which of the following represents the application of the “scientific method”?

a. comparing one experimental subject to one control subject

b. believing an explanation that is too complex to be tested

c. using controlled experiments to test falsifiable hypotheses

d. developing one testable hypothesis to explain a natural phenomenon

e. observing a once-in-a-lifetime event under natural conditions

Expert Solution
Summary Introduction


A scientific method is an investigative approach where scientists conclude some observations about the natural world. They work towards an explanation of the observation and then test them by acquiring more information. The grad school teachers describe the scientific method as a linear and stepwise procedure for observing and explaining the natural phenomena.

Explanation of Solution

Justification for the correct answer:

Option (c) is “using controlled experiments to test falsifiable hypotheses.” This option is correct as the application of the scientific method requires inquisitiveness and curiosity. The scientific method is a framework or protocol which is adopted by researchers for learning in a scientific manner. The first step in this procedure is making an observation on which the questions are framed, and then a hypothesis is made.

A hypothesis is an educated guess, which is based on prior knowledge that is testable under a certain set of conditions that make it useful. Thus, it is just a tentative explanation of the subject. It can be proven to be false by conducting proper research and experiments, so that a more reasonable and accurate explanation about a case under study can be ascertained. Hence, option (c) is the correct answer.

Justifications for the incorrect answers:

Option (a) is “comparing one experimental subject to one control subject...
