We have our list here inside the function data. We're going to transform this into a new list called ndata.

And what they do is they average out all of the numbers from all of those analysts.

Calculates the average in a column of a database specified by a set of conditions for values that are numbers

Mean height

Otherwise it doesn't work.

So in the first exercise, we will calculate the mean of data.

The variance is a measure of how far the data is spread.

It consists of multiplying the values in the first diagonal and subtracting the product of the second diagonal.

B Balance left and right volumes

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

So we're doing this with a for loop.

Let me just briefly summarize what we're doing.

Smoothed lines

In the clustering coefficient of a graph, you have to sum all the nodes in the graph.

Now we're doing it in matrix form.

For the prior probability of each cluster center we just take the sum over all the e ijs, over all data points divided by the total number of data points.

Average

If we subtract 18 from these data sequence, we get 11, 20, 14, 5, and 0.

Now, this is, more or less, if you look at the average data of the countries they are like this.

We take two patches one from the left image, one from the right image.

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

There are really no teenagers at this party. There's either toddlers or small children or parents.

So the T statistic that we could derive from that is going to be our mean, 17.17 minus the true mean of our population.

They are really easy formulas for fitting data to Gaussians, and I'll give you the result right now.

That line is broken up into 32 squares.

Let's practice this. I'll give you a couple of quizzes now.

So, intuitively speaking, the formulas are really easy.

And you've probably seen these before.

What doesn't work is you can't solve the problem for both of these cases and then put these solutions together for example, by averaging.

What we saw in that trial is that that the life expectancies of both groups so the chemotherapy treated group and the Tumor Treating Field group was the same.

So keeping these formulas in mind, here's a quick quiz, which I ask you to actually calculate the mean and variance for a data sequence.

They're exposed to chemicals like chloropicrin, which was originally used as a nerve gas.
