These insects are widely distributed throughout Japan.

So we plot data for sample on this.

This kind of blanket needs good airing.

So first let's revisit this normal distribution.

Dispersion of the normal distribution

Mean of the distribution

Your purse?

This tells you the height of the normal distribution function.

Finally the shape of this distribution of sample means will be approximately normal even if the distribution in the population isn't normal.

Thus, I suspect that each of these examples was distributed according to a normal distribution or

little higher than if you do it, uh, orally. So we looked at this histogram before.

Let me ask the hard question now.

Linear middle of the distribution

Standard deviation of the distribution

Degrees of freedom for the t distribution

You learned something really important.

With 15 different experiments and under the null hypothesis probably goes 0.9.

And, there's a standard deviation of the distribution of sample means, standard air.

What we're going to do, is assume that the feature,

And I have to explain to you, the top of this graph shows you that frequency distribution that I talked about.

It's one standard deviation in the distribution of sample means. So this distribution of sample means, again.

Mean value of the normal distribution

Middle value in the normal distribution

Putting it in population parameters, but putting it in sample statistics.

Then we have a Gaussian distribution that is centered around zero, because that's Mu.

And so therefore, their kinetic energy can be characterized by a velocity dispersion.

0 density, 1 distribution

So I can get any value less than 20 given this distribution.

MV is the linear middle of the distribution.

STD is the standard deviation of the distribution.

Standard deviation of the normal distribution

That's largely influenced by the sample size.

In this video, I'd like to talk about the Gaussian distribution, which is also called the normal distribution.

If you remember from lecture two when we started to talk about probability, we can use the normal distribution.

Intuitively speaking, this is the case because we actually gain information.

She'll need to go through and check the frequency distribution of different intervals.

What I want to do in this video is to generalize it.

That's called a probability histogram.

Mode 1 returns the one tailed test, Mode 2 returns the two tailed test.

Mean value of the standard logarithmic distribution

T distribution.

Here are our equations again.

And similarly, you know,

Other people thought it was funny.

Now what is going to be the variance?
