I have 100 pages of a tedious book to read. I decide each day to read 10% of the pages remaining, rounding up any fractional pages to a whole page.
100 --> 90 --> 81 --> 72 --> 64 --> ...
How many days will it take me to read the whole book?
The way I like to think about it is we're subtracting -1/n of the observation when we subtract the sample mean. Since we do this n times for each observation, n times -1/n equals 1. We are effectively subtracting 1 observation. This is why we effectively have n-1 observations.

@edsouthall Increasing student's understanding of maths by developing their subject specific vocab has been an interest of mine for a while. I came across this 'pack' early on from AISD Elementary Mathematics Department. A great starting point. https://t.co/GZ7gh3ETOW
Please Can anyone explain what is happening graphically/algebraically when you swap the upper and lower limits when integrating? @Whitehughes @Ridermeister@MathsImpact@blatherwick_sam
