comment Histogram with skewed data
Thanks for the ideas. I'm just doing this somewhat manually in Excel. I'm more concerned that if I vary the bin width, then visually, on first perceptions it appears as though some areas are more dense than they really are, simply because it contains more points. Thinking I might just split this particular data into two groups and deal with it that way.

comment Fourier transform for dummies
Here's a video I made a while ago describing the fourier series and fourier transform. It's a bit of a light hearted approach. youtube.com/watch?v=Qm84XIoTy0s

thanks again. I have finally worked through your solution and arrived as a $\pm$ value. See my updated question as I still have some queries I am uncertain of.

Provided better data for the table, clarified some of the algebra letters, and provided an update.

comment Finding uncertainty in the slope/intercept for a non-linear least squares fit
Thanks for that. Just wanted to check that in your last equation you intended $\hat\sigma$ and not $\hat\sigma^2$. So $\hat\sigma$ is $\sqrt{\hat\sigma^2}$

Thanks for that. I'm not familiar with the notation, but it's making some sense. Wondering though, what is $\hat\sigma$

comment Finding points along a plot in Matlab
@macydanim: One more small question. What would I need in order to match a polynomial to it instead of finding a straight-line match?
