Final answer:
Momentary Time Sampling is a technique used for intermittent observation of behaviors in groups. It is similar to PLA-CHECK and is not continuous monitoring. Examples include convenience sampling, systematic sampling, and systematic random sampling for data collection.
Step-by-step explanation:
The method of data collection referred to as Momentary Time Sampling is used for observing and recording behavior within groups at specified moments in time. This technique does not continuously monitor behavior; instead, it involves brief, intermittent checks to see if a particular behavior occurs at that precise moment. The answer to the question provided is not explicitly listed among the options. However, this method is often used in situations such as observing classroom engagement or employee productivity and could be considered similar to PLA-CHECK, which is a method for examining the presence or absence of specific behavior within a group at particular intervals.
Looking at the examples provided:
- The woman handing out questionnaires in the airport is using a non-probability sampling technique, likely convenience sampling, as she selects participants based on their immediate availability and apparent free time.
- The teacher who selects specific rows to check homework is using a systematic sampling method, with a specific pattern or rule determining the sample (every student in rows two and five).
- The health club survey involving every tenth customer is an example of systematic random sampling, where a fixed periodic interval (every tenth customer) is used to select participants for the survey.
In general, the types of data collection methods can include qualitative and quantitative approaches, with quantitative data being further classified into discrete and continuous data based on whether the data can take on only fixed values (discrete) or any value within a range (continuous).
