Week 5 : BIAS

[Cass_i]

I'm a med student. Having a lecture that uses actual studies and explains it so simply helps me not only to understand the content, but to be able to interpret them when I see them anywhere. This is why I chose your content over many others. Thank you so much

Clear, informative and straight to the point, making things crystal clear.

Thank you for the video, can you help me how to prove that is unbiased in this question? Question: Compare the average height of employees in Google with the average height in the United States, do you think it is an unbiased estimate? If not, how to prove it is not matched?

isn't 86/2181 the risk of CHD? or is it in this case that prevalence and risk are same? I have worked with 2x2 tables and have always seen people using prevalence with exposure and risk with disease. Please let me know. Thanks.
