1. What is statistics best defined as?
A. The study of pure mathematics only
B. The science of collecting, organizing, analyzing, and interpreting data
C. A branch of accounting
D. The recording of historical events
B. The science of collecting, organizing, analyzing, and interpreting
data — Statistics is the science of collecting, organizing, analyzing, and
interpreting data to make decisions.
2. A population, in statistics, refers to:
A. Only the people who respond to a survey
B. The average of all data values
C. A small subset chosen for convenience
D. The entire group of individuals or objects of interest
D. The entire group of individuals or objects of interest — A
population is the complete set of individuals or objects a study is meant to
describe.
3. A sample is best described as:
A. A graph of the data
B. A guess about the data
C. A subset of the population used to draw conclusions about the whole
D. The entire population
C. A subset of the population used to draw conclusions about the
whole — A sample is a portion of the population selected for analysis.

4. A parameter is a numerical measure that describes:
A. A graph
B. A sample only
C. A population
D. A hypothesis
C. A population — Parameters describe populations, while statistics
describe samples.
5. A statistic is a numerical measure that describes:
A. A population only
B. A sample
C. A parameter
D. A census
B. A sample — Statistics are computed from sample data and used to
estimate parameters.
6. Descriptive statistics involves:
A. Making predictions about a population from a sample
B. Only collecting raw data
C. Organizing, summarizing, and presenting data
D. Testing hypotheses about unknown parameters
C. Organizing, summarizing, and presenting data — Descriptive
statistics summarizes and presents data through tables, graphs, and
numerical measures.
7. Inferential statistics involves:
A. Only creating charts and graphs
B. Recording data without analysis
C. Calculating the mode only
D. Using sample data to draw conclusions about a population
D. Using sample data to draw conclusions about a population —
Inferential statistics uses sample information to make generalizations or
predictions about a population.
8. Qualitative (categorical) data consists of:
A. Data collected from experiments only
B. Measurements that can be averaged
C. Non-numerical labels or categories
D. Only whole numbers
Page 2 of 46
, Elementary Statistics
C. Non-numerical labels or categories — Qualitative data describes
categories or qualities, such as eye color or gender.
9. Quantitative data consists of:
A. Numerical measurements or counts
B. Colors used in a graph
C. Names of survey respondents
D. Only categorical labels
A. Numerical measurements or counts — Quantitative data represents
counts or measurements that can be numerically analyzed.
10. Discrete data can take on:
A. Any value within an interval
B. Only a countable/finite number of values
C. Only negative values
D. Only categorical labels
B. Only a countable/finite number of values — Discrete data results
from counting and takes on a finite or countably infinite number of values.
11. Continuous data can take on:
A. Only two possible values
B. Only categorical labels
C. Any value within a given range or interval
D. Only whole numbers
C. Any value within a given range or interval — Continuous data results
from measuring and can take any value within an interval.
12. Which level of measurement classifies data into categories with no
meaningful order?
A. Ratio
B. Ordinal
C. Interval
D. Nominal
D. Nominal — Nominal data consists of unordered categories, such as
blood type or gender.
13. Which level of measurement ranks data but has inconsistent
differences between values?
A. Interval
B. Ordinal
Page 3 of 46
, Elementary Statistics
C. Nominal
D. Ratio
B. Ordinal — Ordinal data can be ordered, but the intervals between ranks
are not necessarily equal.
14. Which level of measurement has meaningful differences between
values but no true zero?
A. Ratio
B. Ordinal
C. Interval
D. Nominal
C. Interval — Interval data has equal intervals but lacks a true zero point,
such as temperature in Celsius.
15. Which level of measurement has a true zero point, allowing ratios
to be meaningful?
A. Ratio
B. Interval
C. Ordinal
D. Nominal
A. Ratio — Ratio data has a true zero, so statements like 'twice as much'
are meaningful (e.g., weight, height).
16. A simple random sample is one in which:
A. Every member of the population has an equal chance of being selected
B. Every tenth person is chosen
C. Only volunteers are chosen
D. Groups are selected instead of individuals
A. Every member of the population has an equal chance of being
selected — A simple random sample gives every possible sample of a given
size an equal chance of being selected.
17. In systematic sampling, a researcher:
A. Divides the population into strata and samples from each
B. Only samples people who volunteer
C. Selects every kth individual from a list after a random start
D. Groups the population into clusters and samples entire clusters
