Given:
Ten students from each of the 15 sections of college algebra were asked about the quality of textbook used in the course.
Types of sampling:
Random Sampling:
Every member of the population has an equal chance of being chosen.
Simple Random Sampling:
Every sample of the population has an equal chance of being getting selected.
Stratified Sampling:
Members of the populations are divided into two or more subgroups which have similar characteristics like gender, age or ethnicity, are termed as strata.
Cluster Sampling:
Population is divided into separate groups termed as clusters which have same characteristics that of entire population and then random sample of clusters are chosen from the population.
Systematic Sampling:
Every ${n}^{th}$ member of the population is selected.
Convenience Sampling:
The “convenient” sample is selected from the population.
Since a group of 10 students were selected from each 15 sections of Algebra which act as strata and 10 students are randomly selected from strata all have same characteristics, thus this scenario uses stratified sampling.
Conclusion:
Ten students from each of the 15 sections of college algebra were asked about the quality of textbook used in the course, the study uses stratifidd'sampling method.
