Multiple Choice Questions (MCQs)
1. Which of the following best defines statistics?
A) The study of financial trends
B) The science of collecting, analyzing, interpreting,
and presenting data
C) The art of creating graphs
D) The study of probability only
Answer: B
Rationale: Statistics involves the entire process of
handling data, from collection to interpretation.
Options A, C, and D are incomplete or specific
subsets of statistics.
2. Descriptive statistics is primarily concerned with:
A) Summarizing and presenting data
B) Making predictions about populations
C) Calculating probabilities
D) Designing experiments
,Answer: A
Rationale: Descriptive statistics focuses on
summarizing data. Option B relates to inferential
statistics.
3. Inferential statistics:
A) Summarizes data using tables and graphs
B) Uses sample data to make conclusions about a
population
C) Is not used in business applications
D) Only deals with percentages
Answer: B
Rationale: Inferential statistics allows predictions
and conclusions about populations using sample
data.
4. Which type of data classifies items into categories
without ranking?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
, Answer: A
Rationale: Nominal data categorizes without a
meaningful order. Ordinal data has ranking; interval
and ratio are numeric.
5. Temperature measured in Celsius is an example
of:
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Answer: C
Rationale: Interval data has equal intervals between
values but no true zero. Ratio data has a meaningful
zero.
6. Which level of measurement has a true zero and
allows ratios?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
