Welcome back to statistics.
Today we do a case study in regression.
In this case study, I will use again the data that you all submitted
about my current weight called L and my previous weight from last year
as you guessed it all in kilograms called P.
Here is my question for you as a well-trained statistician.
What is the very first thing I'll do?
Compute the mean, the variance, and similar simple statistics?
Run a scatterplot?
Or go straight to the end and run my regression methods
to see what's the best line that fits the data? Pick one.
