  • Scary Pumpkin Statistics

    Scary Pumpkin Statistics

    Students predict the number of seeds in a pumpkin and then count the seeds. They use chi square analysis to accept or reject the null hypothesis.

  • Corn Chi Square (remote)

    Corn Chi Square (remote)

    This is the remote version of a classroom activity I do with corn ears. Students would count the kernels (smooth, wrinkled, purple, yellow) and determine if the ears of corn are the result of a dihybrid cross, RrPp x RrPp. This gives students the opportunity to apply statically analysis to data sets and determine if…

  • Corn Genetics and Chi Square Analysis

    Corn Genetics and Chi Square Analysis

    Students count kernels on an ear of corn. The corn is the product of a dihybrid cross, so that the phenotype of the kernels will follow a 9:3:3:1 ratio.

    Chi Square Analysis

    The new Advanced Placement Biology curriculum includes a few topics on statistical analysis under the section on Science Practices: “Students can use mathematics appropriately.”  Most introductory level biology classes (freshman) do not include these lessons because it can be difficult with students who haven’t advanced very far in algebra.   Seniors in  AP Biology should…
