STRATIFIED, SYSTEMATIC, and CLUSTER Random Sampling (12-4)
To create a Stratified Random Sample, divide the population into smaller subgroups called strata, then use random sampling within each stratum. Strata are formed based on members’ shared (qualitative) characteristics or attributes. Stratification can be proportionate to the population size

Stephan Mescher (3/10/22): Geodesic complexity of Riemannian manifolds
Geodesic complexity is motivated by Farber’s notion of topological complexity of a space, which gives a topological description of the motion planning problem in robotics. Motivated by this, D. Recio-Mitter recently introduced geodesic complexity as an isometry invariant of geodesic spaces

Gender Stratification: Crash Course Sociology #32
Today we’re looking at how society becomes stratified along gender lines. We’ll discuss Raewyn Connell’s concept of hegemonic masculinities and emphasized femininities. We’ll explore gender socialization in the home, media, and schools. Finally, we’ll explain how gender stratification resu
