FCI pre-test comparison: Cuesta College (fall semester 2019)

Students at Cuesta College (San Luis Obispo, CA) were administered the 30-question Force Concept Inventory (David Hestenes, et al.) during the first week of instruction.

Student's t-test of the null hypothesis between pre-test scores from these two lab sections results in p = 0.49 (t = −0.693, sdev = 4.45, degrees of freedom = 54), thus there is a significant difference between the early and late afternoon lab sections.
