12CAFS - Research Methodology: Sampling

Which statement best describes the aim of research? Mark only one oval.

• To utilise a variety of research methodologies

• To predict the relationship between two factors

• To advance knowledge and increase understanding

• To identify a particular area of interest to be investigated

Which practice would be most appropriate when creating a sample group? Mark only one oval.

• Identifying a large number of participants who share the same point of view

• Selecting participants that represent a cross section of the population

• Targeting participants who will adequately support the hypothesis

• Choosing a small number of participants to produce fast results

Which of the following is the best type of sampling when conducting research? Mark only one oval.

• Selecting a cross-section of the population that is representative of the group

• Selecting ten per cent of the population using a convenience sampling process

• Selecting no more than ten people from the specific area of research you are investigating

• Selecting a large number of people from the population so everyone has an equal chance of being selected

Oliver has been given a task where he must distribute ten questionnaires. Oliver selects ten of his family members to complete the questionnaire. Which sampling method is Oliver using to complete the task?

• Cluster

• Convenience

• Random

• Systematic

Which of the following best describes systematic sampling?

• Selecting participants at a random starting point and then at a fixed, periodic interval

• Dividing the population into clusters and then selecting one cluster group to participate

• Dividing the population into various cluster groups and then randomly selecting participants

• Selecting individuals at random from the list of volunteers already obtained from the population

A researcher creates a sample group that does not represent a cross-section of the population. How would this affect the quality of the research?

• The data would lack validity.

• The conclusions would be unbiased.

• The process would lack respect for the participants.

• The process would break anonymity and confidentiality agreements.

Which of the following best describes stratified sampling?

• Each individual in the population is chosen entirely by chance.

• Individuals are selected at regular intervals from the population.

• The population is divided into subgroups and only individuals in certain subgroups are randomly selected.

• The population is divided into subgroups and individuals are then randomly selected from each subgroup.

Which of the following is a true statement about sampling?

• It is a secondary research method.

• It ensures the hypothesis is always correct.

• It allows findings to be applied to the group being investigated.

• It gives an opportunity to interview all individuals affected by the research topic.

Which of the following is an advantage of sampling when conducting research?

• It guarantees subject participation.

• It allows the researcher to collect digital data.

• It increases the amount of information collected.

• It provides the researcher with a cross-section of the population.
