Abstract
In traditional introductory Statistics courses, statistical inference is often not introduced until the last third of the course, leaving little time for students to develop a strong understanding of the meaning of a p-value. We use simulation and randomization methods to introduce statistical inference early in our introductory Statistics courses, which allows us to discuss concepts of statistical investigations, significance, and p-value in week 1. We start with one-proportion examples to build on students’ intuition about “Is the observed result surprising, if both outcomes are equally likely?” Having established the core concept of the logic of inference, we repeat the cycle for situations involving one mean, two proportions, and so on, to contexts involving several proportions, several means, and two quantitative variables. Here we describe the implementation of this approach by showing examples of our student activities, and demonstrating our use of applets to bolster student understanding and learning.
