Question 1

what are populations?

Answer 1

The population is the group of people to whom the research directly applies

Question 2

what are samples?

Answer 2

Because we can’t usually do a study that involves every member of a population of research interest, researchers will instead try to find a sample that is representative of the population.

Question 3

what are the three sampling methods?

Answer 3

Convenience sampling
Random sampling
Stratified sampling

Question 4

what is Convenience sampling ?

Answer 4

Convenience sampling involves selecting participants who are readily available to the researcher. It is less likely to provide findings that are representative of the population.If volunteers are used in a study, this is always convenience sampling.

Question 5

what is Random sampling ?

Answer 5

Random sampling involves giving each member of a population (of research interest) an equal chance of participating in the study

Question 6

what is Stratified sampling ?

Answer 6

Stratified sampling is used when a study seeks to represent particular groups in the same proportion as a population. The population is divided into distinct groups (strata) and then the sample is drawn from each stratum

Question 7

what is Participant allocation?

Answer 7

The process of assigning participants from the sample into experimental groups is called allocation.

Question 8

what is the control group?

Answer 8

The control group is not exposed to the IV and therefore provides a base-line comparison to validate the conclusions relating to the experimental group

Question 9

what is the experimental group?

Answer 9

The experimental group is exposed to the IV, and is therefore the source of material relating to the experimenter’s hypothesis
