Question options:

I believe the options to the question are:

a) The random sampling technique used to recruit the participants

b) The number of people in the sample

c) The use of three measured variables

d) The number of significant findings

Answer:

a. The random sampling technique used to recruit the participants

Explanation:

The random sampling technique would be considered under the review of external validity of the study.

Why? The external validity as opposed to the internal validity of a study determines how much the results or conclusions of a study can be applied outside the context of that study. The random sampling technique would reveal how sampling was conducted and whether it reflects an objective/impartial study.
