,📘 Chapter 1: Statistics, Data, and Statistical Thinking
Multiple-Choice Questions (21)
1. Statistics is best defined as:
A. The study of accounting principles
B. The science of collecting, analyzing, interpreting, and presenting data
C. The use of computers to process numbers
D. A branch of economics
✅ Correct Answer: B
Rationale: Statistics focuses on data—how it’s gathered, analyzed, interpreted, and communicated
for decision-making.
2. Which of the following is an example of descriptive statistics?
A. Testing a hypothesis
B. Estimating a population mean
C. Creating a frequency table
D. Calculating a confidence interval
✅ Correct Answer: C
Rationale: Descriptive statistics summarize and organize data without making predictions.
3. Inferential statistics is primarily used to:
A. Summarize known data
B. Draw conclusions about a population from a sample
C. Organize data visually
D. Eliminate sampling error
✅ Correct Answer: B
Rationale: Inferential statistics uses sample data to make generalizations about a population.
4. A population is:
A. A group of sampled observations
B. All individuals or objects of interest in a study
C. A random variable
D. Always finite
✅ Correct Answer: B
Rationale: A population includes every member relevant to the study.
5. A sample is:
A. The entire population
B. A subset of the population
C. Always larger than the population
D. Free of bias by definition
✅ Correct Answer: B
Rationale: A sample is selected from the population to represent it.
, 6. Which variable is categorical?
A. Age
B. Income
C. Brand preference
D. Temperature
✅ Correct Answer: C
Rationale: Categorical (qualitative) variables describe attributes or categories.
7. Quantitative variables are:
A. Non-numeric
B. Descriptive only
C. Numeric and measurable
D. Always discrete
✅ Correct Answer: C
Rationale: Quantitative variables represent numerical measurements.
8. Discrete variables:
A. Can take any value within an interval
B. Are always fractions
C. Take countable values
D. Cannot be numeric
✅ Correct Answer: C
Rationale: Discrete variables involve counts (e.g., number of customers).
9. Continuous variables:
A. Are always integers
B. Have gaps between values
C. Can take any value in a range
D. Are categorical
✅ Correct Answer: C
Rationale: Continuous variables include measurements like weight or time.
10. Data measured as labels only are:
A. Ordinal
B. Nominal
C. Interval
D. Ratio
✅ Correct Answer: B
Rationale: Nominal data classify observations without order.
