Geometry, Statistics, Probability: Variations on a Common Theme
geometry seems to be the natural way to emphasize the unity of the fundamental ideas. I can verify visualizations are very helpful, not sure if that’s the same as all of geometry, but I think that’s where we’ll end up at the end of this. there are not really that many formulas; there are however…

Not sure if I’ll keep to the Chapter 1 reading or jump onto next week’s reading. I think I’d like to skim this and then move on. anomalies emerge slowly because of the difficulties in perceiving them … by investigators working within the “worldview”… Wow this is long.

I wonder also how long this thinking will go on inside our head, before transforming into computation in a machine, with a Man Thinking to guide it. It…

Week 0 is winding down, and as I sit here am a bit sleepy. a z score gives the location of a score in terms of the number of standard deviations above or below the mean. the standard error of the mean What does standard error mean again? The expected deviation of a sample mean…

Right? through repeatedly drawing samples of the same size from a population. So yes, but this repeatedly might be important. One of the useful functions of sampling distributions is to characterize how sample statistics relate to…

If you’re hypothesis is correct, you have a theory. Is that right? Theory sure has taken on bigger meaning since 4th grade. This I should already…
