If the observed value of the sample statistic is not unlikely to have occurred from
the chance model, then the chance model is a plausible explanation for the
observed data.
The chance model considered in this section involved tossing a fair coin. This chance model
allowed for assessing whether an observed number of “successes” in a study provided strong
evidence that the two outcomes of a categorical variable were not equally likely. In the next
section you will consider other chance models, but the reasoning process will remain the same.
