Probability is the measure of the likelihood of an event occurring, and in this case, when conducting tests of statistical significance, it is used to calculate the likelihood that the observed difference between two groups or variables is due to chance. A low probability value indicates a low likelihood that the difference is due to chance and suggests that the result is statistically significant. Percent variance, coefficient of correlation, and standard deviation are measures that can be used to analyze and describe data, but they do not directly give the odds that the observed difference is due to chance.
