Overview of Statistics
True / False Questions
LU
1. Statistics is the science of collecting, organizing, analyzing, interpreting, and
presenting data.
True False
2. Inferential statistics refers to generalizing from a sample to a population, estimating
XE
unknown parameters, drawing conclusions, and making decisions.
True False
3. Descriptive statistics refers to summarizing data rather than generalizing about the
population.
True False
LI
4. Estimating parameters and testing hypotheses are important aspects of descriptive
statistics.
BR
True False
5. Inconsistent treatment of data by a researcher is a symptom of poor survey or
research design.
True False
6. Empirical data are collected through observations and/or experiments.
AR
True False
7. Business intelligence refers to collecting, storing, accessing, and analyzing data on
the company's operations in order to make better business decisions.
True False
Y
8. When a statistician omits data contrary to her findings in a study, she is justified as
long as the sample supports her objective.
True False
9. A strong correlation between A and B would imply that B is caused by A.
True False

, 10. The post hoc fallacy says that when B follows A then B is caused by A.
True False
11. A statistical test may be significant yet have no practical importance.
True False
12. Valid statistical inferences cannot be made when sample sizes are small.
True False
LU
13. Statistics is an essential part of critical thinking because it allows us to transform the
empirical evidence from a sample so it will agree with our preferred conclusions.
True False
14. Statistical challenges include imperfect data, practical constraints, and ethical
dilemmas.
XE
True False
15. A business data analyst needs a PhD in statistics.
True False
LI
16. The science of statistics tells us whether the sample evidence is convincing.
True False
17. Pitfalls to consider in a statistical test include nonrandom samples, small sample size,
BR
and lack of causal links.
True False
18. In business communication, a table of numbers is preferred to a graph because it is
more able to convey meaning.
True False
AR
19. Statistical data analysis can often distinguish between real vs. perceived ethical
issues.
True False
20. Excel has limited use in business because advanced statistical software is widely
Y
available.
True False
21. Statistics helps surmount language barriers to solve problems in multinational
businesses.
True False
