Given
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.

Which of these types of sampling is used: random, stratified, systematic, cluster, convenience?
Explanation:
It is given that,
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
That implies,
Since Stratified random sampling is a method of sampling that involves dividing a population into smaller groups–called strata.
Then, the random sampling used is Stratified Random Sampling.
