    When doing hypothesis testing we have two ways of making a decision - the critical value method and the p-value method. While both give the same results in terms of determining whether to reject or not reject the null hypothesis, most statistical analysts prefer the p-value method.

    The critical value method basically sets a criterion on a number scale. If your observed score falls beyond that critical value on your scale of measurement, you reject your null hypothesis.

    The p-value method also uses a criterion, but this is based on the area under the curve, or the probability of obtaining a score. If the ...
