Sample DSST Principles of Statistics Practice Questions

Try these sample questions to test your DSST Principles of Statistics exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A researcher records the blood type of each person in a sample as A, B, AB, or O. What level of measurement is being used?
A.Nominal
B.Ordinal
C.Interval
D.Ratio
Explanation: Blood type labels place people into named categories with no natural order. That is nominal measurement because the values classify observations but do not rank or measure quantity.
2Students rate a campus service as poor, fair, good, or excellent. Which measurement level best describes the ratings?
A.Nominal
B.Ordinal
C.Interval
D.Ratio
Explanation: The response choices have a meaningful order from poor to excellent, but the spacing between choices is not known to be equal. Ordered categories without guaranteed equal intervals are ordinal data.
3Which variable is quantitative rather than categorical?
A.Favorite news source
B.Number of credit hours completed
C.College major
D.Type of housing
Explanation: The number of credit hours completed is numerical and arithmetic operations on the values are meaningful. The other choices name groups or labels rather than measuring an amount.
4A professor computes the average quiz score for all 28 students in one class section. In this situation, the 28 students are best described as what?
A.A statistic
B.A sample
C.A population
D.A sampling frame error
Explanation: If the question of interest is that one class section, then all 28 students in the section make up the population. A statistic summarizes a sample, but here every member of the defined group is included.
5A pollster wants a random sample of voters from a city and selects every 50th name from a complete voter-registration list after a random starting point. What sampling method is this?
A.Cluster sampling
B.Systematic sampling
C.Convenience sampling
D.Voluntary response sampling
Explanation: Selecting every kth individual after a random start is systematic sampling. It can work well when the list is not ordered in a way that creates a pattern related to the variable being studied.
6A researcher divides a university into class years, then randomly samples students from each year. Which sampling design is being used?
A.Stratified random sampling
B.Cluster sampling
C.Snowball sampling
D.Judgment sampling
Explanation: The class years are strata, and the researcher samples from every stratum. Stratified sampling is often used to ensure that important subgroups are represented.
7An online survey about commuting is posted on a city website, and only visitors who choose to respond are counted. What is the main source of bias?
A.Random sampling error
B.Voluntary response bias
C.Blinding bias
D.Matched-pairs bias
Explanation: People decide for themselves whether to respond, so those with strong opinions or unusual experiences may be overrepresented. This is voluntary response bias.
8A clinical trial randomly assigns participants to receive either a new treatment or a placebo. What is the primary purpose of random assignment?
A.To make the treatment group larger than the placebo group
B.To reduce systematic differences between groups before treatment
C.To guarantee that every participant improves
D.To remove the need for statistical analysis
Explanation: Random assignment helps balance both known and unknown characteristics across treatment groups. This makes differences in outcomes more plausibly attributable to the treatment.
9For the data set 4, 6, 6, 8, 11, what is the mean?
A.6
B.7
C.8
D.11
Explanation: Add the values to get 35, then divide by the five observations. The mean is 35/5 = 7.
10The salaries at a small startup are 42,000, 45,000, 47,000, 50,000, and 250,000 dollars. Which measure of center best resists the influence of the very high salary?
A.Mean
B.Median
C.Range
D.Standard deviation
Explanation: The median is resistant to extreme values because it depends on the ordered middle position. The very high salary pulls the mean upward much more than it changes the median.

About the DSST Principles of Statistics Exam

DSST Principles of Statistics is a Prometric-administered credit-by-exam covering foundations of statistics, probability, correlation and regression, sampling distributions, and inferential statistics. The official fact sheet lists 100 questions in a 2-hour testing window, permits a non-programmable calculator, provides a standard normal table in the exam, and lists an ACE-recommended minimum score of 400 for 3 lower-level baccalaureate semester hours. Colleges set their own DSST credit policies, so candidates should confirm acceptance with their institution before testing.

Assessment

Multiple-choice exam; the official fact sheet says all sample test questions use one correct answer and three incorrect options. A non-programmable calculator and a standard normal table are permitted/provided under the official fact sheet.

DSST Principles of Statistics Study Tips from Top Performers

1Study all five official content areas because the fact sheet weights Foundations of Statistics, Probability, Correlation and Regression, Sampling Distributions, and Inferential Statistics at 20% each.
2Practice descriptive statistics and visual displays first; they support later questions about probability, standard error, and inference.
3Memorize core probability conditions and rules, including independence, conditional probability, combinations, permutations, expected value, and common discrete and continuous distributions.
4Work regression questions by interpreting slope, intercept, residuals, r, r^2, and prediction limits rather than only memorizing formulas.
5Be comfortable converting sample means and proportions into z or t statistics and interpreting standard error.
6Use a non-programmable calculator and a z table during practice so your workflow matches the official calculator and standard-normal-table policy.
7Confirm your school's DSST credit policy and required score before scheduling or paying for the exam.
