Final answer:
Momentary Time Sampling is a reliable system for a teacher to collect data on a student's behavior despite attention being diverted elsewhere, and it is TRUE that it could be suitable in this situation. Different sampling methods, including convenience and random sampling, have their own implications for the validity of research findings.
Step-by-step explanation:
It is TRUE that Momentary Time Sampling might be a good measurement system to recommend in the example where a teacher is struggling to collect data on a student's independent work behavior due to constant attention shifts. Momentary Time Sampling is a form of behavior observation methodology that involves observing a behavior during a part of the interval or moment in time. This approach allows for the collection of data at predefined times, which could be more practical for a teacher with limited time to continuously observe a student. The data gathered through this method can then be used to make inferences about the student's overall independent working behavior.
For collecting data on student behavior or any other research purposes, different sampling techniques can have a significant impact on the findings. Commonly used sampling techniques include convenience sampling, systematic sampling, cluster sampling, and random sampling. Each method carries its own set of implications, with convenience sampling often being the easiest but potentially the least representative of the population, while random sampling is generally more representative but can be more difficult to achieve.
To ensure the reliability and validity of data, it is crucial that researchers and educators, follow correct data collection procedures and carefully select the sampling technique that most appropriately suits the research design and constraints.
