Question

What sampling technique is employed when the English department calculates the average final grade by selecting the first 300 students' final grades sorted αbetically?

a) Simple Random Sampling
b) Stratified Sampling
c) Systematic Sampling
d) Convenience Sampling

Answer 1

The sampling technique used is Convenience Sampling, where the first 300 students sorted alphabetically are selected without a random process, unlike methods such as Simple Random Sampling or Stratified Sampling.

Step-by-step explanation:

The sampling technique employed when the English department calculates the average final grade by selecting the first 300 students' final grades sorted alphabetically is d) Convenience Sampling. Convenience sampling involves selecting samples that are easiest to access, and choosing students based on their position in an alphabetical list adheres to this method, as it does not require a random process.

In contrast, Simple Random Sampling would require every student to have an equal chance of being chosen, typically using a random number generator. Stratified Sampling would involve dividing the entire population into different subgroups and then taking a proportional sample from each subgroup. Systematic Sampling would require selecting every nth individual from a randomly ordered list. Lastly, Cluster Sampling would involve randomly selecting entire groups or clusters of individuals to sample from.
