26:20 FYI for those still watching this video, there is an error at 26:20! The Pearson correlation coefficient is D -0.2 because the dots are scattered with a "weak negative correlation". Answer choice E -1.0 would have all the dots in a straight line with a "strong negative correlation". Check First Aid 2019 page 263 for more information

​@@UnknownStar08 Relative risk is for cohort studies. We know this is a cohort study because we have an outcome of prostate cancer and are looking retrospectively to see whether an exposure had some influence in occurrence of prostate cancer. In this case, the exposure is presence or absence of children. With relative risk, you are looking at the risk of something between two groups. Because we are interested in comparing prostate cancer risk in men without children to men with children, we look at the risk of just prostate cancer in men without children (what we are interested in) and then compare to (divide by) prostate cancer in men with children. Risk of prostate cancer in men without children: Prostate cancer and no children (80) divided by total men without children (1000) Compare it (divided by) by the risk of men with prostate cancer with children. Risk of prostate cancer in men with children: Prostate cancer with children (220) divided by men with children (1500) So it should look like: Risk of prostate cancer in men without children (80/1000) / (220/1500) Risk of prostate cancer in men with children.

Thank you for posting your videos! I'm one of those non-traditional student and haven't seen or attempted any stats questions since the mid 90s. I would start sweating as soon as I saw a biostats question on any of my practice blocks. Originally, I would pick an answer and move on to the next question. I've stopped skipping them, and they no longer send into the panic zone. THANK YOU!

This video (and the accompanying one), is a MUST WATCH for anyone preparing for step 1! Simplified and to the point. Thank you Dr. Neil!

Dr. Neil's biostatistics review videos are an absolute must-watch for Step 1 studying! These lectures will give you an approach that you can consistently use to answer questions correctly. Forever grateful!
