The probability of making a Type I error is denoted by alpha and the probability of making a Type II error is denoted by beta. The value that we calculate to assess whether the difference is likely due to chance is called the p-value, which is the chance of the observed group difference (or something more extreme) assuming the true group means were the same. The NIH Roadmap constitutes an important vehicle for generating change—a most critical element of this plan is the reengineering of the national clinical research enterprise. Experimental design.
