Biostatistics

The use of mathematics to investigate life science related problems

Biostatistics is a field of science that uses mathematics to investigate a number of life science related problems, including those pertaining to genetics, medicine, biology, agriculture, and environmental health.  Biostatistics uses algorithms, graphical tools, and statistical models and methods for a variety of applications, including the analysis of DNA sequence data and clinical trial results.

Teacher Resources

Iceland’s Genetic Database: Good or Bad Idea? (PDF 28.17 KB, Lesson Plans/Lesson Activities)

Description: This lesson examines issues stemming from genetic databanks and population genetics studies.

Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics (Lesson Plans/Lesson Activities)

Description: A lesson that requires students to work through a series of questions pertaining to the genetics of sickle cell disease and its relationship to malaria. These questions will probe students' understanding of Mendelian genetics, probability, pedigree analysis, and chi-square statistics.

Retinoblastoma, Cystic Fibrosis, and Body Mass Index, Oh My! (PDF 196.72 KB, Lesson Plans/Lesson Activities)

Description: Building on their intuitive understanding of twin study correlations, students analyze subsets of data to determine how strong the environmental and genetic influences are for three different traits/conditions. Students use mean, standard deviation, and Pearson correlation coefficient to describe and make meaning of their data. They also graph their data and correlations, and compare the results from their subset of data to the results of a group using a different subset of the data.
