Document Summary
6. 1 "test scores" and error rates: hypothesis testing. Establish your null distribution and test statistic. Conduct the statistical test: decide on a significant threshold under the null hypothesis. This is called the a-value: calculate the probability of your sample mean under the null hypothesis. This is called the p-value: compare these two probabilities or test scores (t observed and t critical) If p a or t(o) t(c), then we reject the null hypothesis. If p > a or t(o) a or t(o)
