Question

to test a hypothesis about a given variable, experimental and control groups are tested in parallel. which of the following best explains the dual experiments?

Answer 1

The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."

What is experimental design?

• The process of deciding which variables to use in an experiment to test a particular hypothesis is called experimental design.
• To properly collect data and evaluate the hypothesis, the experimental design method is used.

Now,

• A specified variable is changed in the experimental group in a well-known fashion.
• That selected variable is left unaltered in the control group so that comparisons can be conducted.
• Control variables are variables that are utilized in an experiment to serve as a baseline against which the data from the experimental variables are gathered and evaluated (which is why the other answers are incorrect).
• In the experimental group, it is advisable to modify just one variable at a time so that any differences from the control group may be quickly linked to the one variable that was altered.

Hence, amongst all the given options, The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."
