Assign participants randomly to an experimental or control group B. Give the experimental group some type of experience that might change their behavior C. Observe the possible effects of the experimental condition D. Publish the results.

Answer 1

Answer:

The step that should come first is A. Assign participants randomly to an experimental or control group.

Explanation:

It turns out that the sequence of the options given is the very sequence in which the whole experiment should take place. When using the experimental method, the first thing the researcher must do is assign the participants to either an experimental or a control group. Such assignment should be done randomly to make sure each participant will have equal chances of belonging to either group. That will make results more trustworthy.

The control group will not be introduced to the experience that might change their behavior, only the experimental group will. Then, the results of each group will be measured to observe the possible effects of the experimental condition. Finally, the results will be published to confirm or deny the experience's influence.
