What type of sampling bias occurs when a sample is taken from a population that is easily accessible rather than randomly selected?

Back

Convenience Bias

Front

What is the term for a sampling method that fails to include a portion of the population, leading to an unrepresentative sample?

Back

Undercoverage Bias

Front

What sampling method involves assigning numbers to each member of a population and using random selection to choose a sample?

Convenience Sampling

Front

What is the difference between a sample and a population in research?

Back

A sample is a subset of individuals selected from a larger population, which is the entire group of interest.

Front

What is the importance of random sampling in research?

Back

Random sampling helps ensure that every individual has an equal chance of being selected, reducing bias and increasing the representativeness of the sample.

Front

What is a potential drawback of convenience sampling?

Back

Convenience sampling can lead to biased results because it may not accurately represent the entire population.

Front

What is the purpose of using a control group in an experiment?

Back

A control group serves as a baseline to compare the effects of the experimental treatment, helping to isolate the variable being tested.

Front

What is the term for a systematic error that occurs when certain groups are systematically excluded from the sample?
