1. Basic Ideas
Question 1:
What is the primary purpose of statistics?
A) To collect as much data as possible
B) To make sense of data by summarizing and analyzing it
C) To create complex mathematical models
D) To eliminate all variability in data
PAGE 1
,Answer: B) To make sense of data by summarizing and analyzing it
Explanation:
Statistics is primarily concerned with collecting, summarizing, analyzing, and interpreting data to make
informed decisions.
Question 2:
Which of the following is a population parameter?
A) Sample mean
B) Sample standard deviation
C) Population mean
D) Sample median
Answer: C) Population mean
Explanation:
A population parameter is a numerical characteristic of a population, such as the population mean.
Question 3:
What distinguishes descriptive statistics from inferential statistics?
A) Descriptive statistics involve making predictions, while inferential do not
B) Inferential statistics summarize data, while descriptive statistics make predictions
C) Descriptive statistics summarize data, while inferential statistics make predictions or inferences about a
population
D) They are essentially the same
Answer: C) Descriptive statistics summarize data, while inferential statistics make predictions or inferences
about a population
Explanation:
Descriptive statistics describe the main features of a data set, whereas inferential statistics use samples to make
generalizations about a population.
Question 4:
Which level of measurement includes data that can be ordered but not measured?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
Answer: B) Ordinal
Explanation:
Ordinal data can be ordered or ranked, but the intervals between ranks are not necessarily equal.

, Question 5:
In statistics, what is a variable?
A) A fixed value
B) An outcome that can take on different values
C) A summary statistic
D) A type of graph
Answer: B) An outcome that can take on different values
Explanation:
A variable is any characteristic, number, or quantity that can be measured or quantified and can take on different
values.
Question 6:
Which of the following is NOT a type of variable?
A) Discrete
B) Continuous
C) Categorical
D) Static
Answer: D) Static
Explanation:
Variables are typically classified as discrete, continuous, or categorical. "Static" is not a standard type of variable
in statistics.
Question 7:
What is the difference between a sample and a population?
A) A sample is larger than a population
B) A population is a subset of a sample
C) A sample is a subset of a population
D) They are interchangeable terms
Answer: C) A sample is a subset of a population
Explanation:
A population includes all members of a defined group, while a sample consists of a part of the population used to
represent the whole.
Question 8:
Which term describes the likelihood that a result is not due to random chance?
A) Bias
B) Variability
