Linear Regression: How does salinity of the ocean relate to depth?

Students in an introductory ecology and evolution lab collected water salinity measurements at various depths of the ocean at the Cal Poly Pier in Avila Beach, CA. Each student collected their own data and then worked through the attached activity to investigate correlation and simple linear regression. Use lab worksheet linked here. If your students

Mendelian Genetics Lab

Co-developed lesson on Medelian Genetics used in an Introduction to Cell and Molecular Biology class.  Students use a chi-square test (simulation and theory-based) to compare their observed phenotype data (leaf and stem color) to the hypothesized distribution (Mendal’s second law). Data are pooled across 8 lab groups. Use lab write-up here.

Sensitivity and specificity: understanding shortcomings of antibody tests with the COVID-19 virus

Sensitivity and specificity are commonly taught concepts in biostatistics courses. The article linked here gives a nice visual explanation of false positives and false negatives with tests that do have high sensitivity and specificity, but a low infection rate of the disease in the population.

New Biology activities on genetic drift and using randomization-based inference

Jeff Ploegstra’s presentation at Iowa Science Teacher’s Section (ISTS) looks at an overview of the “new biology” with examples of projects worked on with students utilizing large data sets requiring inferential statistics, algorithmic thinking, and comfortability interfacing with common databases to make predictions and draw conclusions. Also in the presentation are example exercises that could

BIO 162 Plant Signaling Experiment

This activity includes the logistics to run the lab through a 10 week course along with a homework that makes use of the multiple means applet. The lab entails comparing plant growth with medium amounts of fertilizer and high amounts of fertilizer. Information from this experiment sets the stage for the students to design their

BIO 162 Activity on ANOVA

This activity uses the multiple means applet to explore four data sets and how variability between, variability within, and sample size affect the interpretation. Data Worksheet

Chi-square activity

This activity looks at the distribution of heart attacks over the days of the week. It starts out looking at those who are employed, but there is an extra data set that looks at those who are not employed. Comments from participants at our Morro Bay workshop are left in to see the discussion between

Activity on fatty acids and genetics

Another activity to use with biology students looking at linear and non-linear genetic models and connecting to disease modes of inheritance. Sample activity on fatty acids and genetics

Tree species activity from workshop in Morro Bay, California

The kick off workshop for being more intentional about teaching statistical thinking in undergraduate biology courses was held September 7th & 8th in Morro Bay, California. Some of our tangibles from that workshop are now coming in and this post contains an activity that you may do with your biology students. We have also provided

What to post?

What might a user of the STUB Network want to post? Do you have a question about the best context to use for teaching a statistical test? Do you wonder if there is a best pedagogy for teaching a certain topic, or concept, or statistical test in your class? What are some pitfalls that others
