The Stem and Tendril project consists of a collection of projects for use in statistics laboratories. Each project covers multiple levels of the curriculum, pedagogically, they are held together by a common theme. Students should be able to use these materials at many different levels of development. By coming back to similar data stories at different levels of awareness, the student should be able to fully understand the previous material and better learn the new material.

    A new project based on a data set on crackers

    The data set crackers of Carolyn Cuff gives a theme to a new project that covers many of the basics of exploratory data analysis including numeric summaries of univariate data, graphical summaries of univariate data, correlation, fitting simple linear regression models, and data extraction by index and logical vectors (indicator variables).
