Scatterplots and Line of Best Fit

[|Will Women Outrun Men?]- link to an activity for creating scatterplots and lines of best fit. Shows the importance of the limits of extrapolation as it shows that in the year 6419 female marathon runners will reach the speed of sound.

-Found this online- data already provided for students to create a scatterplot and find the line of best fit.

-4 problems for students to use graphing calc to find a line of best fit.

-"real" data comparing homework assignments turned in and class grades. Asks students to create a scatterplot, draw a line of best fit, determine the equation for that line, and use the information to support whether the data has a correlation.

- data collection to determine the amount of time it might take for the wave to go around the superbowl. I use this when I am initially teaching students how to use the graphing calculators to find a line of best fit. We do a "regular" wave, slow wave, super fast wave, wave with a twist, etc. I usually do 4-5 data points for each set. The superbowl part usually ends up being an extension. This has the seating chart for the 2010 Superbowl.

-Activity that uses data from 1987-2010 to make predictions for the average cost of a Thanksgiving meal for 10.

Activity I found on a [|blog]: Rolling Marker Lab: We set up 'ramps' of different heights (folders propped on books), rolled markers down and measured the distance traveled. It was a nice review of scatter plots, best fit lines and the different equations used to describe lines. We had some fun building crazy ramps and trying to find markers which would roll in a straight line
