The curriculum introduces variables, percentiles, levels of measurement, distributions, and key mathematical tools such as summation notation, linear transformations, and logarithms. It builds skills through statistical literacy and exercises, then progresses to graphing techniques, distribution summaries, bivariate description, and introductory probability concepts, supporting a systematic understanding of data and uncertainty.","Introduction to Statistics  \nOnline Edition  \nPrimary author and editor: David M.
