Convenience sampling

Definition

Convenience sampling is a non-probability sampling method where samples are taken from a group that is easy to access or contact. This method often results in biased data as it does not represent the entire population.

5 Must Know Facts For Your Next Test

1. Convenience sampling is often used due to its ease and cost-effectiveness.
2. It can lead to significant biases because the sample may not be representative of the population.
3. This method does not allow for generalizations about the population since it lacks random selection.
4. Convenience sampling is useful for exploratory research where precision is not critical.
5. Results from convenience sampling should be interpreted with caution, given the potential for bias.

Related terms

Random Sampling:

A probability sampling method where every member of the population has an equal chance of being selected, ensuring a representative sample.

Bias:

A systematic error that occurs when certain members of a population are more likely to be included in a sample than others, leading to unrepresentative results.

Stratified Sampling:

A probability sampling technique that involves dividing the population into subgroups (strata) and taking random samples from each stratum.
