Week 6 Research Methods

What is the first step in the process of collecting quantitative data?

• Administering the data collection process

• Selection of study participants

• Collecting data

• Selecting a data collection instrument

Which type of sampling ensures every member of the population has an equal chance of being selected?

• Nonprobability sampling

• Systematic sampling

• Stratified sampling

• Probability sampling

Which sampling method involves selecting every nth individual from a population list?

• Stratified sampling

• Systematic sampling

• Cluster sampling

• Snowball sampling

What is crucial to avoid bias in systematic sampling?

• Choosing a large sample size

• Using a random number generator

• Randomly ordering the population list

• Selecting multiple sample groups

In stratified sampling, what does the researcher do after identifying subgroups?

• Chooses the largest subgroup only

• Uses simple random sampling within each subgroup

• Uses convenience sampling for selection

• Ignores subgroup sizes

Which of the following is not a probability sampling method?

• Snowball sampling

• Simple random sampling

• Stratified random sampling

• Cluster sampling

What type of sampling is most affected by the researcher's discretion and availability of subjects?

• Random sampling

• Probability sampling

• Nonprobability sampling

• Stratified sampling

What should be obtained from institutions before conducting a study on their premises?

• Financial support

• Sampling frame

• Required permissions

• Public recognition

Which sampling approach involves participants referring other potential participants?

• Systematic sampling

• Stratified sampling

• Snowball sampling

• Simple random sampling

What is a key advantage of having a larger sample size in quantitative research?

• It simplifies data collection

• It reduces sampling error

• It eliminates the need for analysis

• It decreases the cost of research
