There are ___ basic techniques for sampling individuals from a population: probability sampling and non-probability sampling.

two

1

In ____ sampling, each member of the population has a specific probability of being chosen.

probability

2

In ____ sampling, we don't know the probability of any particular member of the population being chosen.

non-probability

3

4

In ____ ____ sample, the population is divided into subgroups (aka strata), and random sampling techniques are then used to select sample members from each stratum.

5

Stratified random sampling has the advantage of a built in assurance that the sample will ____ reflect the numerical composition of the various subgroups.

accurately

6

When is important to represent a small group within a population, researchers will "____" that group to ensure that a representative sample of the group is surveyed.

oversample

7

Rather than random sampling from a list of individuals, the researcher can identify "clusters" of individuals and then sample from these clusters.

Cluster sampling.

8

Non-probability sampling are quite ____. A population may be defined, but little effort is expended to ensure that the sample accurately represents the population.

arbitrary

9

One form of non-probability sampling is ____ sampling, which could be called a "take them where you find them" method of obtaining participants.

Haphazard

10

A second form of non-probability sampling is ____ sampling. The purpose is to obtain a sample of people who meet some predetermined criterion.
