Today you guys split up into groups and took data on 10 fun size bags of M&M's. You should have taken data on several variables including: weight of bag, # of M&M's per bag, # of each color, etc.
In class you completed a set of questions dealing with the graph of the Weight vs. # in each bag, and found the regression line for this data. We will discuss this data tomorrow, and use the Starbucks data to create another plot.
Coming up:
- No Homework for tonight, unless you did not finish your Graph in class
- Midterm next week!
Posting for Points:
What does the correlation coefficient tell us about a graph?

the correlation coefficiant tells us how close the points on the graph are to being in a straight line
the correlation coefficiant tells us how close the points are to being in a straight line, dpending on its closeness to 1
It tells us how close the points on the graph are to being a straight line. The closer they are to 1, the better they fit.
Depending on its closeness to one, the correlation coefficiant tells how accurately we can predict what happens in the future
the correlation coefficiant tells us how close the points on the in the line. The closer to one the number is the closer the points are to each other.
