Let's find out just how much taper should be added to the jaw bore

A common measure of intelligence, IQ, is distributed with a mean of 100 and a standard deviation of 15.

Let's now consider linear regressions of standard scores.

Standard deviation of the distribution

There's variance in the sample SD squared.

Sample standard deviation

STD is the standard deviation of the distribution.

Standard deviation of the normal distribution

We also applied it to 10,000 people. Our average loss in this case was 20 pounds.

This is just simple algebra. So here's the formulas for Z, that's from

Standard deviation for the total population

We add those up we get 250 and now we divide by 5 to get back our 50.

And I'll just call this, what's the probability that I land between 1 standard deviation the mean is minus 5 one standard deviation below the mean is minus 15 and one standard deviation above the mean is 10 plus minus 5 is 5.

Then, I want you to fit a Gaussian using the maximum likelihood estimator.

If there's one thing you want to take home from this class that is that as you get more data as a statistician, your confidence increases so your confidence interval shrinks, whereas of course more data doesn't change the standard deviation.

That's all taken care of.

Look, this C.D.C. thing, Lori, it's a mistake.

So, we have the some of the squares and we have the cross products.

And finally, this is the inverse of the standard score z that I've told you.

But after we take the square root, it only gets bigger by 1.5 since the square root of 1.5 squared is equal to 1.5.

It looks like it's like 80 something percent, maybe 90 percent roughly.

And sometimes it's easier to think in terms of sigma.

See, I'd been guilty all this time of what's termed 'speciesism'.

And if we want to take it to the next level and figure out the standard deviation, the standard deviation is just the square root of the variance, which is equal to the square root of p times 1 minus p.

And that's not fair.

It is equal to the square root of the sum of the deviations in the y's over the deviations of the x's.

What are the mean and standard deviation of this distribution of the distance between the initial position and the final position?

We have 10,000 people who received Treatment A. Their average loss is 10 pounds.

Since Yi is just the individual observation Xi multiplied by 1.5, it's 1.5 times 9, which is 13.5.

This is the standard deviation.

And then these two lines I drew right here, these are 1 standard deviation below and 1 standard deviation above the mean.

I'm perfectly sober. Charming simplicity.
