What is good about Tom finding opinions in this way (opportunity sampling)?
How to approach this question
Think about the practical advantages of opportunity sampling. Why would a researcher choose this method despite its flaws? Consider time, cost, and effort.
Full Answer
It is quick, easy, and inexpensive to collect the data.
The main advantages of opportunity sampling are practical. It allows a researcher to gather data with minimal effort, time, and expense. Tom can likely collect his 100 responses in a single afternoon without needing to travel extensively or prepare complex sampling frames. While it has significant statistical weaknesses (like bias), its primary benefit is convenience.
Common mistakes
✗ Stating a statistical advantage, as there are very few. For example, saying "it is representative" would be incorrect.
