Lesson
Module Objectives: Visualize variability in a quantitative attribute using dot plots, boxplots and histograms Informally describe a distribution of data in terms of group properties: range, distribution shape, and center Locate a central range of “typical” values (central clump, middle 50%) Use distribution shape to decide which best represents the center, mean or median Recognize bimodal distributions as such, and informally describe their variability (range, shape, and center) Recognize that the amount of variability influences how certain you can be when making predictions about the data <center>![Kids Playing]600 Kids playing — Variability in height, weight, arm size, and foot length </center>
