(10 points) several bulleted paragraphs; use your text and the YES Observational Studies and Bias lab exercise to discuss the five specific types of selection bias.
Be thorough and specific and discuss the five types of selection bias possible, even if the researchers did not address them. This is where you will apply critical analysis to bias. 11.

— Be thorough, specific, and discuss the four types of selection bias possible, even if the researchers did not address them. This is where you will apply critical analysis to bias. 12.
