  • Frame - the list of all restaurant locations in the chain.
  • Sample - the 10 randomly selected locations.
  • Control group - subject group 2.
  • explanatory variable - organic cleaner.
  • response variable - bacterial growth.

What are some terms in research?

The population is total set of items that a sample is drawn from and in this case it all the restaurants. The sample would be the selected items from the population.

The control group is the group that is not manipulated by the explanatory variable which is the organic cleaner. The response variable is what changes as a result of the explanatory variable so it is bacterial growth.
