Experiencing Sampling Variation Early and Often in an Intro Statistics Course
Using data centric lessons and visualization tools such as the "Points and Densities Little App" have supported my students’ understanding of the key role sampling variation plays in statistical investigation. I love overhearing “Hey, my sample looks different from yours!” It opens the door to explore whether there is still a consistent story to tell about a variable.
Join me as we look at an early lesson in my course introducing the language common, unusual, and rare while using standard deviation and z-scores. Although the lesson has a focus on describing common and rare events, it allows students to experience and make sense of sampling variation. These experiences early in an Intro Stats course lay a useful underpinning for introducing later inferential statistical concepts such as the confidence interval.
