Crash Course: Statistics #10 - Observational Data Collection

Today we’re going to talk about good and bad surveys.

From user feedback surveys, telephone polls, and those questionnaires at your doctors office, surveys are everywhere, but with their ease to create and distribute, they’re also susceptible to bias and error.
