Population distribution is geographically where the populations are concentrated/not concentrated/clustered, etc. Where exactly are the populations?

Density of population is simply the total number of individuals divided by the given area. For example, if the population of a random country is 10,000,000 people, and the countries total area was 1,000,000 km^2, the pop. density is 10 people/km^2. Doesn't take into account of their distribution.

"sample" is a specific number of individuals, chosen/selected for whatever researchers are looking for

A valid "sample", out of a university population of 3,000, would be, let's say 100 respondents.

That means that those 100 people who answered your questions will represent the 3,000 students.

sample= number of people who represent the general population

We use "samples" because interviewing everybody would take too long, and it would be too expensive.

Distribution: how race, ethnicity, religion, or whatever you are looking at, is spread around on an area

population: all the people living in a specific area

Example:

There's a dense Mexican-American population distributed across Southern California, Arizona and Texas.
