Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of central tendency of the class data, and then graph and interpret the results. (less)

Collaborative Statistics was written by Barbara Illowsky and Susan Dean, faculty members at De Anza College in Cupertino, California. The textbook was developed over several years and has been used in regular and honors-level classroom settings and in distance learning classes. This textbook is intended for introductory statistics courses being taken by students at two– and four–year colleges who are majoring in fields other than math or engineering. Intermediate algebra is the only prerequisite. The book focuses on applications of statistical knowledge rather than the theory behind it. The textbook is also available in printed form from Qoop.com. (less)

In this lesson, learners will practice graphing and statistically analyzing data. In the first part of the lesson, they will survey items in their homes that use energy; a worksheet is given to each learner that includes multiple choice questions related to energy consumption that will determine their energy audit scores. Depending on their grade level, learners will use all the audit scores from the group to find the mean, median, mode, range, upper quartile, or/and lower quartile. After the numbers have been analyzed, the group may review why it is important to reduce energy consumption and may think of ways to conserve energy. This lesson is standards-based and includes worksheets written in Chinese and resources for educators. (less)
