- It is prone to bias because it relies on the subjective judgment of the researcher.
- Commonly used in exploratory research where generalization to a larger population is not a primary concern.
- Results from convenience samples cannot be generalized to the entire population due to lack of randomness.
- This method is often used in pilot studies or preliminary research to quickly gather data.
