but the equation that the curve fit provides is way off.

Hi. You didn't provide your equation. As a side note, another program gave a caution message...
"The abscissae are not distinct."

Re-looking at your data, is this a typo, or did you intend to have an x value with the possibility of having two different y values?

Again, it was just a caution message.

I'm trying to do a polynomial curve fit (order 2) for the data below, but the
equation that the curve fit provides is way off. Any ideas why this isn't
working? It works for a similar set of data...
