Step 1
I'll solve this problem by explaining the key differences between convenience sampling and voluntary sampling in research methodology.

Step 2
: Define Convenience Sampling

A convenience sample is a non-probability sampling technique where researchers select participants based on their easy accessibility and proximity. Participants are chosen simply because they are convenient and readily available to the researcher. Key characteristics: - Easiest method of sampling - Participants are selected based on proximity or ease of recruitment - No systematic selection criteria - Often used in preliminary studies or pilot research

Final Answer

Both methods can introduce significant sampling bias and are generally not recommended for generating statistically representative research findings.
