Based on the researchers' methodological choice, identify the category of sampling they are employing and explain why this approach impacts their ability to generalize their findings to the entire student body.
Case context: A research team is designing a study on the study habits of undergraduate students. They decide to use a sampling approach that does not rely on structured random selection from a clearly defined population, which they note is the most common approach used in general psychological research.
Question: Based on the researchers' methodological choice, identify the category of sampling they are employing and explain why this approach impacts their ability to generalize their findings to the entire student body.
Sample answer: The researchers are employing non-probability sampling. This approach impacts their ability to generalize their findings because the lack of structured random selection limits their ability to make perfectly representative population estimates.
Key points:
- Identifies the method as non-probability sampling.
- Notes the absence of structured random selection.
- Explains that this limits the ability to make perfectly representative population estimates.
Rubric: Award full credit for correctly classifying the method as non-probability sampling and explaining that its lack of structured random selection prevents perfectly representative population estimates.

Which of the following best defines non-probability sampling in psychological research?
Match each aspect of non-probability sampling with the statement that best explains its role or limitation within psychological research.
A researcher investigating the relationship between sleep and academic performance recruits participants by asking for volunteers from their own Psychology 101 classes. Because the researcher cannot mathematically specify the chance that any individual student in the entire university population will be selected for the study, this is an example of non-probability sampling.
A researcher studying personality traits recruits participants by handing out surveys at a large national gaming convention. Arrange the logical steps required to analyze and classify this sampling method based on the principles of research design.
What is the primary reason that non-probability sampling is the most common approach used in general psychological research?
In psychological research, non-probability sampling is considered the ideal method for generating perfectly representative population estimates.
A scientist concludes that a new cognitive intervention is universally effective for all adults after testing it only on a convenience sample of volunteers from their own university. When evaluating the validity of this universal claim, a critic would argue that the use of _____ sampling makes it impossible to mathematically specify selection probabilities, thus fundamentally limiting the study's ability to provide a perfectly representative estimate for the entire global population.
Match each psychological research scenario with the specific non-probability sampling technique it exemplifies.
A developmental psychologist recruits participants for a study by placing flyers in local daycare centers. In analyzing the limitations of this study, the researcher must recognize that because non-probability sampling does not rely on structured random selection, it limits the ability to make perfectly representative population _____.
Evaluate a researcher's sampling methodology by arranging the steps in the correct logical sequence to determine if it is a non-probability method and identify its key limitation.
Define non-probability sampling as it is used in psychological research and describe its primary limitation regarding population estimates.
Based on the researchers' methodological choice, identify the category of sampling they are employing and explain why this approach impacts their ability to generalize their findings to the entire student body.
If a psychologist designs a study using the most common sampling approach in general psychological research, what specific mathematical specification will they be unable to make regarding their target population?
