BUS5112 Unit 3 Graded Quiz — Sampling Methods
25 Questions with Verified Answers | Score: 96/100
Question 1:
Which of the following statements best describes the difference between a population and a
sample in business research?
A) A population is the entire group of interest, while a sample is a subset selected from that group
to represent it.
B) A population is a measured subset of a group, while a sample is the theoretical entire group.
C) A population only refers to human participants, whereas a sample can include products or
financial records.
D) A population is always infinite, while a sample is always a finite number of observations.
Answer: A
Explanation:
In research terminology, a population represents the complete collection of all elements (people,
items, data points) that share a common characteristic of interest. Because studying an entire
population is often impractical or too costly, researchers draw a sample—a smaller, manageable
subset—to make inferences about the whole population.
, Question 2:
A regional bank wants to assess customer satisfaction across its 50 branches. Instead of
surveying all 200,000 customers, the research team selects a list of 5,000 customers to receive
the survey. In this scenario, what does the group of 200,000 customers represent?
A) The sampling frame
B) The sample
C) The target population
D) The sampling unit
Answer: C
Explanation:
The 200,000 customers represent the target population, which is the entire group the bank wants
to draw conclusions about. The 5,000 selected customers form the sample. The sampling frame
would be the actual list or database from which the 5,000 names were drawn, which ideally
matches the target population.
Question 3:
To ensure that every employee in a corporation has an equal and independent chance of being
selected for a workplace culture survey, the HR department assigns a unique number to each of
the 1,200 employees and uses a computer program to randomly generate 150 numbers. Which
sampling method is being used?
A) Systematic sampling
B) Stratified sampling
C) Convenience sampling
D) Simple random sampling
Answer: D
Explanation:
This is the classic definition of simple random sampling. Every individual in the population has a
known, equal, and independent probability of being chosen. Using a random number generator on
a complete list of the population is the standard way to execute this method, minimizing selection
bias.
