stats identification rev

A group where members have something in common, that is, the total set of observations that can be made.

It is a smaller group or subset of the population in question.

Describes an entire population.

Describes only the sample.

Simplest way of getting a random sample where each member of the population has an equal chance of being chosen as the sample.

It involves selecting a simple random sample from each of a given number of subpopulations. Each subpopulation is called a stratum.

Population is first divided into separate groups called clusters. Then, a simple random sample of clusters from the available clusters in the population is selected.

The value of k is first calculated by dividing the population size by the sample size.

Two or more probability techniques are combined. It can be described as sampling within the sample.

Used to decide whether the null hypothesis should be rejected in a hypothesis test.
