HELPFUL RANDOM STUFF
6.2 homework, #13
Calculating several z-scores at once using StatCrunch
HERE'S A STATCRUNCH STEP-BY-STEP GUIDE!
***I constructed these step-by-step StatCrunch guides for YOU!
and (there are 3)- https://www.youtube.com/watch?v=gEEC9JEqDss
Video 1 starts with additional examples of The Emperical Rule and Chebyshev's Theorem
Video 1 - Quartiles and the five-number summary
Video 2 starts with section 3.4
Video 3 starts with section 3.5. We compare the two data sets.
These regression videos are based on these data sets: commute time vs. well-being, bear length vs. bear weight, credit score (FICO) vs. interest rate.
Video 1 is half of the class where the other video was consumed by the camera. Greedy bugger. It's about r values and scatterplots.
Video 2 starts with some homework questions about r values and z-scores. We discuss the overall steps of the linear regression process.
Video 3 starts with some estimation and goes through the total overall error.
Video 4 begins with a regression homework problem and finishes up the process started in video 3.
