Hi
Welcome to Joey's website!
Chapter 5
-
Where did I struggle? At first I got confused on how to calculate the total sum of square and the coefficient of determination.
-
What questions do I still have? What is a better way between residual plot and line of best fit to show outliers.
-
What am I going to do to strengthen my understanding? I should read the book more and look for a lot of examples and exercises.
Two key things you learned from this unit. (What are your understandings? What are you taking away from this? What real world applications have you seen? What links to other subjects did you see?)
-I learn about the characteristic of correlation and able to explain the graphical display statically.
-I also learn about danger of extrapolation that we should not estimate y value that isn't within the x values.
This is biggest project we've had so far for the AP Stats class. We had to do an experiment to see whether finger length affect how fast people type. The point of this project is to learn about correlation and be able to find the mean, quartile range and many more.
