RE: [tips] Hey! Good At Problem Solving? Maybe You Can Win A Prize!
This is how I see it: (1) Get bunches of different sized animals and calculate the size and weight of the animals (I write "size" because one would probably want a single number that reflects height, width, and depth). (2) Calculate the correlation across species of "size" and weight. Determine for which species the correlation is large and for which it small/weak. (3) Using a examples from different bunches of animals, has a person use magnitude estimation to guess the weight. Compare estimates made for animals where the correlation is strong and animals where the correlation is weak. (4) Step 3 above should indicate how much error there is in the estimates for the two groups of animals, which would suggest a "correction" or "fudge" factor that is added/subtracted from the initial estimate. NOTE: first establish how precise the weight estimate has to be, that is, what is an acceptable error margin. Just a starting point but I have the feeling that men and women have been sizing each other up for a lng time and they might be reasonably accurate at estimating weight. :-) One could also interview the carnies who guess weights at sideshows about how they do it but they might not want to give such secrets away.;-) -Mike Palij New York University m...@nyu.edu -Original Message- On Thu, 01 Mar 2012 10:21:17 -0800,, Marie Helweg-Larsen wrote: Yeah - I want to win $50,000 and since I know nothing about pigs or live animals or how one could estimate their weight from afar I seem to be a perfect candidate for solving the problem (and I'm also a woman which should improve my odds).

RE: [tips] Simulation of Marie's "Funny" Correlations
The other difficulty with the scatterplots is, when you are correlating two 5-point scales, there are a limited number of xy coordinates on the scatterplot and various numbers of cases can be hiding under each score. Marie's scatterplots evidenced some attempt to illustrate the number of cases at each coordinate (with bolding and some random spread of the plotted dots) but it still isn't as clear as it would be with a more continuous scale. So, some method of illustrating the number of cases at each coordinate would be helpful in seeing the pattern that resulted in an overall negative correlation from two separate subgroups with positive correlations. One thing that will make this pattern clear is including the three trendlines or lines of best fit with both individual data sets and the overall combined set. This will show the clear barbell pattern with the overall trendline going from upper left to lower right and each individual Red and Blue trendline going from lower left to upper right intersecting the overall trendline at different points (the Blue at a higher point on the y-axis on the overall negative trendline than the Red). Plotting the red mean xy coordinate (which is near the center of the plot) and the blue mean xy coordinate (which is closer to the upper left hand corner of the plot) will also show how offset the two groups are.
