Now what happens when you change the standard deviation.

It's the quadratic deviation from the mean.

Test are just the average squared error, or one half of the average squared error on my training validation and test sets without the extra regularization chart.

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.

And so, you know, the variance, I'm gonna estimate as just the average of the square differences, between my examples, minus the mean.

It should also produce descriptive statistics that look like this. Again, these are from

To show ourselves this, let's just redo the calculation.

Remember, every sample statistic is just a point estimate.

Mu is the mean, or the average.

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

Z scores, then we know what percentage of scores fall in certain ranges.

I've got in my example minus the mean, minus the center, minus the mean of distribution.

To see this, recall that a is equal to y bar b x bar, but for a standard score, zₓ always has a mean of 0 and zᵧ has a mean of 0, because we subtracted out their means.

From the mean to one standard deviation above, and one standard deviation below.

I know that's a mouthful. So, you might wanna replay that.

Notice that this method will also reveal the bias in the wand measurement.

T statistic from this.

You evaluate it at plus 5, which is right here.

There's variance in the sample SD squared.

Average

Can you guess what the effect is of adding 1000 to your salary on the mean and the standard deviation?

The variance by its very nature computes in the quadratic.

This is what factory workers earn in an hour in Indonesia on average, 20 cents.

Um, but sometimes, you do see, if you rely on the Summary

It's in the straight middle, because these two variances are the same, so we just average the means.

We know that the average after four exams, at four exams, is equal to 84.

Mean of the distribution

less than 17.17 minus the mean, which is less than 2.13.

So what is the mean over here?

looked at different types of histograms to get the feel of different shapes of distributions.

These were the results for Jeremy Lin.

If there is a big difference then this is a larger value and we know for the day in question what the mean and the standard deviation is for this percentage change.

To compute this, recall that b equals the sum of the product of the difference of the x's from the mean and the y's from the mean divided by the square difference between x and the mean
