Key Terms
This is theoretically specified aggregation of study elements. What is this?
Population
This bias is the unwarranted generalization of research findings to the population as a whole when one gender is not adequately represented in the sample. What is this?
Gender Bias
This indicates a type of random sampling in which procedures for sample selection are strictly based on chance and each case has an equal chance of being selected. What is this type of sampling?
Simple Random Sampling
This indicates a type of nonprobability sampling in which cases are selected based on their availability to the researcher
Convenience Sampling
This is the aggregation of elements from which the sample is actually selected. What is this?
Study Population
This bias is the unwarranted generalization of research findings to the population as a whole when one culture or ethnic group is not adequately represented in the sample. What is this?
Cultural Bias
This indicates a type of random sampling in which the first case from a list is selected and then every kth case on the same list is selected. What is this sampling?
Systematic Random Sampling
This nonprobability sampling indicates the process of accumulation as each located subject suggests other participants. Namely, a researcher selects one member of the population and then asks that person to identify others in the population
Snowball Sampling
This indicates that each element has an equal chance of selection independent of any other event in the selection process. What is this?
Random Selection
This bias occurs when a substantial number of people in a randomly selected sample choose not to participate. What is this?
Nonresponse Bias
This random sampling is used when a list of all members of a population does not exist. This indicates a type of random sampling in which an initial sample of group members is selected, then listed, and the listed members are subsampled, which provides the final sample of members. What is this sampling?
Cluster Random Sampling
This indicates a type of nonprobability sampling in which sampling characteristics are based on elective criteria that define a unique group and targeting knowledgeable individuals/expertise
Purposive Sampling
This is a list from which the elements of the population are selected. Researchers draw their sample from this. What is this?
Sampling Frame
This bias occurs when sampling frames are not consonant to which we seek to generalize. What is this?
Overgeneralization
This indicates a type of random sampling in which a sample is drawn from strata, subgroups defined by a particular characteristic of a sample and the sample population should be proportionate to the whole population. What is this sampling?
Stratified Random Sampling
This indicates a type of nonprobability sampling in which a researcher chooses to sample a subgroup based on a particular demographic to meet the needs of their study
Quota Sampling
What is the primary reason for using probability sampling in a research study?
In order for the sample to represent the characteristics of the population
