This statement explains a type of sampling:

'Participants are chosen in an unspecific order with all participants having an equal chance of being chosen'

• Quota

• Random

• Snowball

• Stratified

Participants are gathered by other participants and so on until a full sample is collected

• Random

• Systematic

• Snowball

• Volunteer

Participants choose to take part in the study after seeing an advert or a pop up such as a survey that is sent out by researchers

• Volunteer

• Opportunity/ convenience

• Random

• Quota

Participants are chosen by the research based on the easiest access to them

• Stratified

• Quota

• Snowball

• Opportunity/ convenience

Every nth person in a Target Pop are chosen by the researcher to take part

• Stratified

• Systematic

• Random

• Snowball

Target pop is split into subgroups based on characteristics, the sample is then randomly chosen from each subgroup to take part

• Quota

• Stratified

• Random

• Volunteer

Target pop is split into subgroups based on characteristics, the sample is then carefully chosen from each subgroup to take part based on researchers need

• Quota

• Stratified

• Random

• Volunteer

What is meant by the term "Target population"?

• The group of people that the researcher aims to study

• The people chosen to take part in the study as participants

• The people that complete the study fully and do not drop out

What is a sample?

• The group of people the researcher wants to study

• The group of people taken from the target population to take part

• The people who were not chosen in the target population

Why do we take a sample?

• Because we don't need a lot of people

• Because the target pop is too large to study everyone

• So that we can make it easier for ourselves as researchers
