What is that first thing they teach in statistics?

What? I see an edge. How can you find the center of coloration if there is no edge? I realize that some of the alpha particles may have went further than others, but you can't really see the damage they caused. Most of them gathered forming a pretty sharp ring. The ring is about 11 pixels thick. If you measure from Razd's circle to the edge of that part I pointed about before it's about 11 pixels. (and yes I measured it on the new picture you gave me) If you measure from the edge of the 210 ring to Razd's 210 circle it's about 11 pixels. Obviously some inconsistencies there.

Yup, no knowledge of Gaussian distribution here.

Click on the highlighted phrase above or remain ignorant (and a source of amusement).

And how does that differ from what I said:

"I realize that some of the alpha particles may have went further than others, but you can't really see the damage they caused."

I know all the alpha particles are not all lined up in one spot, but the curve is pretty steep. Meaning there is an edge. Sure there may be an uncertainty of .1 m, but nothing like there is measuring from the center of the ring.

It differs because in English and mathematics 'center' and 'edge' are not the same.

Sheesh, if we have to start at this basic a level of understanding, I don't see how anything productive can happen for some time.

I'll be back if I have something to contribute after you have worked out the difference between center and edge, and why it is important to measure the mean and not the illusive and undefined edge when discussing large amounts of data points that scatter around a mean in the normal curve.

I see the area of uncertainty being wider as to the center of the band than the outer band. Why you guys can't see that; I don't know

Mathematics, scientific integrity, honesty?

Pick one or all.
