b. Since we’d like to make sure the survey represents opinions from students of all ages, we can use stratified sampling.
<u>Probability Sampling
</u>
- In probability sampling each element of the population has an equal chance of being selected for the sample.
- Probability sampling helps us to create a sample that is truly representative of the population.
- A sample that truly represents the population ensures that the statistical conclusions are valid.
<u>Stratified Sampling
</u>
In stratified sampling, the population is divided in different classes that are known as strata. Once this classification has been done, we randomly select a sample.
Since our objective for the survey is to collect opinions from students of all years, we can divide the student population into four strata based on age, and select a probability sample from each stratum.
