Size of the total population

Population size

Number of success overall

We describe to you what our objectives are to differentiate these principles of

Standard deviation for the total population

And suppose that there are only 300 certified wine experts in the entire world.

And our goal in this initiative is to introduce you, all students to the basic principles of pharmacology.

Travel in packs, no way to tell.

Fourth, students must stop traveling in packs.

What the body does to the drug, what the drug does to the body?

We are the most in debt ... obese ... addicted and medicated adult cohort in U.S. history.

And in those examples, it's important that you understand the difference between a population and a sample.

In order to survive Humans have had to organise themselves.

Sampling error clearly depends on the size of the sample so, and, but also the degree of variance in the population.

We are going to go through a series of lectures.

And we always have to deal with this whenever we engage in this process of trying to get a random and representative sample from the population.

The crowd was moving in a solid body.

I'm moving very quickly over a number of disciplines.

We're getting random representative samples from the population to estimate those population parameters.

A group of organ systems working together make up an organism, and a group of the same organisms are a population.

He's being kept in druginduced coma.

A bunch of dirt?

I heard it's a pretty bad outbreak.

So there's a 95 chance that this is true.

If we just know that the probability of success is p and the probability a failure is 1 minus p.

It's also important to know the distinction between parameter and statistic.

It shoots up and it keeps going up.

And living amongst the tangle of tube worms is an entire community of animals shrimp, fish, lobsters, crab, clams and swarms of arthropods that are playing that dangerous game between over here is scalding hot and freezing cold.

I did that once here, and we saw that the mean was about six, right?

They'll fluctuate, right.

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

But it ain't doing both.

They all disappeared!

We've put agent Scott in a druginduced coma.

Remember from the first lecture, we often don't know the population parameters, that's why we're doing the research.

All social animals use some methods of communication to exchange information and to maintain an orderly community.

In the face of the Thought Police, they cannot act collectively.

It's like a pack of wild Cujos ripping up the flesh of the American people. human imitating dog barking Drug lords!

You do find groups in the animal kingdom you do find cooperative groups but these groups are always either very small or they're all siblings.

And we have to duke it out every day, so we resort to politics.

Well, what do you think i've got here now?

I said, I want to do it the right way, with the rubber bands.

lecture two, I'll just start to use examples.

Let's get a random sample.
