To explain: The sampling method used in the study for the given population statement and suggest if any better sampling method can be used.
An interview is conducted at a local high school so it is considered a convenience sampling, where voluntary sampling can also be done, a survey is conducted where all teenagers participated willingly and gave their opinion
Given:
A study is conducted to know the opinion of all teenagers and an interview is conducted at a local high school. The statement given is “all teenagers”
Explanation:
The statement given is “all teenagers”. The population is the set of all objects and the sample is a subset of the population. The study was conducted by interviewing students at a local high school, which is considered as convenience sampling and it does not represent the exact population of all teenagers.
A voluntary sampling would have been better to use as teenagers willingly participate in a survey and give their opinion.
