Doing a Fair Test. It is important for an experiment to be a fair test. You conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same. For example, let's imagine that we want to measure which is the fastest toy car to coast down a sloping ramp.ou conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same.

Of the three tests administered during the Culture Fair session, one is timed, but two are not timed. We generally say the Culture Fair is for persons whose native language is not English, but actually anyone may take the Culture Fair test. Itâs all about the individualâs test-taking preferences.
