Austin Community College is conducting a study to see how faculty feel about the integrity of online courses. Twenty faculty from each of the four major divisions were surveyed. The data from the 80 surveys indicated that more than 75% of the faculty are concerned about the integrity of online courses. Answer the questions that follow:

a. identify the sample of the study

b. identify the population of the study

c. Identify the sampling technique used in the study (simple random, cluster, stratified, systematic, convenience)

Answer 1

a. Sample - 80 faculties that were surveyed
A sample is the subset of population that is surveyed to study some characteristics of the population

b. Population - All faculties in all the 4 major divisions
A population is the group of individuals about which the researcher is studying

c. Sampling technique - Statified sampling
In stratified sampling, the population is subdivided into different strata and samples are drawn from all strata. Here, the 4 divisions are the 4 strata and the samples are taken from all 4 divisions, making this an example of statified sampling.
