Hi, I added on to one of your graphs to predict a winner, on this page.
How should I write the copyright tag so that it won't be deleted?

[edit] encyclopedic
What are you talking about- extrapolation may not be encyclopedic? It's a natural question to ask- you see two lines representing public support of two people that are converging in the distance, and you want to know when they will intersect. Why would you want to remove that answer so that people will not know? If linear interpolation is good enough to show on the scatter plot then surely linear extrapolation is good enough to show also. You're just removing perfectly good information for no reason.
Why don't you just extend your lines until they go past the important primary dates?

By drawing the linear interpolation, you are predicting values of the poll results between the points that were never actually taken, so you are effectively predicting the poll results on past dates when there were no polls. The line itself misrepresents all the values of the poll throughout the plot. The process of extrapolation is less reliable than interpolation but both are valid mathematical approximations to given data. The line you drew is a trend line, and it would be nice if everyone could see the results if the trend continues. Tbsmith (talk) 01:00, 19 December 2007 (UTC)
