So the German JAMA #COVID19 cardiology study that has been referenced thousands of times to shut down the #Big10 and #PAC12 seasons by media including @ESPN presents data that is statistically impossible. Basically everything in this table below is bogus. Let me explain:
For this example I'm going to use systolic blood pressure but it can be anything that was highlighted above by @ProfDFrancis. In the table above, the parentheses mean they found an interquartile range for systolic BP of 125-133 - or 50/100 of their subjects fell in this range.
This is a problem. In a much larger study across the German population the IQR is much larger. For example, if we take the 41-50 age range from this larger study (similar range to the JAMA study) they found a mean of 130.5 and a standard deviation of 16.8.

Version 3 of the #CFBPlayoff rankings were released last night. What you expected? If youve followed along since early Oct you know the process. You werent surprised. For the rest of you, lets take a look & compare to what was projected using the same process used for 5 yrs.
First off, why does the committee use this process? Think about it. 14 busy guys make up this committee. They have roughly 60 hrs from when the last game ends on Sat to when they need to have this Top 25 created on Tues. If they evaluate only 30 teams to get that 25, how much
time is adequate to evaulate? 1 hr? Thats 30 hrs of evaluation. Half the time is gone & no one has slept. The process of getting a consensus out of 14 people hasnt even started. Thats why this process is kept so simple, & its why they have a defined predictable process.
