Question

The principal of a school randomly selects $15$ students to decide the destination for the annual outing. This sampling represents which type of sampling?

• A. Stratified sampling
• B. Random sampling

Answer 1

The correct option is B Random sampling

When each element of a population has equal chance for being selected for analysis, then the sampling is called random sampling.

While in case of stratified sampling, population is divided into sub-population and random elements are chosen from each of them.

Since in the given example, the principal randomly selects $15$ students from the entire school, therefore this sampling represents random sampling.

So, option (b) is correct.
