I'm sorry for the long length and if this post drifts off topic but I felt it would be fair to respond.
So you would expect a curve that looks something like this? (This graph represents contrived data, for demonstration purposes, unrelated to any sightings database anywhere. It was only assembled to demonstrate a set of data that may be indicative of dimorphism among a sampling of some tall unknown animals. This data is in Inches.)
I would try to determine if that blip at 185 inches is statistically significant, except for the fact that I really don't care. If it's important to somebody they can figure it out for themselves.
This may be found to be true when science has collected enough specimens to measure height accurately, within an inch of actual height. Unfortunately our SSR database is much less specific than that. Few reports give a height that is measured in inches.
It sort of appears that the double bell curve changes to a Gaussian curve when the Same Data is presented in feet (rounded down) instead of inches. I guess what I have shown COULD be representative of a unknown primate population that shows traits of dimorphism after all! Does it? I have no way of knowing with our presently available data.
Coincidentally, all of the height data I used for SSR database graphs in this thread are in feet, rounded down, because that is the search functionality that was available to me at the time. I had to go with what was available. (This graph represents contrived data, for demonstration purposes, unrelated to any sightings database anywhere. It is the same data as used in the graph above, but shown in feet, rounded down, instead of inches) When I am in the woods I carry a tape measure. Eventually, when I get a good sighting I will ask Sasquatch to hold still while I measure. We'll get this dialed in!
I still eagerly await the review of my work in this thread by others so that I can learn from my mistakes and possibly become a better person.
