Two complete lessons that use Topic 2.1 from the IB ESS (Environmental Systems and Societies) course to introduce students to descriptive statistics, Students t-test and Chi squared. Each lesson is self contained but could be used anywhere in the course to introduce typical statistical methodologies that are applicable to both the Internal Assessment and Extended Essay.
Each lesson is available in either pdf or epub formats.
Each lesson focuses on theoretical data from about the Forest Elephant populations of the Zakouma National Park in Chad.
In the first lesson Students get to use descriptive statistics to calculate mean, standard deviation and standard error of the mean and use these to investigate variation in mass between male and female elephants.
In the second lesson students use t-values to investigate the confidence of two population means and chi squared to investigate the presence of tusks in male and females and food choice in the whole population.
Each lesson contains step by step walk through methodologies and examples of how to use technology to calculate these values.
While designed to accompany the IB ESS course the lessons could be used in any post 16 curriculum that has an ecology or biogeography element.
