Chapter 1 What is Statistics?
1) A population is a collection of all individuals, objects, or measurements of interest.
2) Statistics are used as a basis for making decisions.
3) A listing of 100 family annual incomes is an example of statistics.
4) The average number of passengers on commercial flights between Chicago and New York
City is an example of a statistic.
5) Statistics is used to report the summary results of market surveys.
6) A sample is a portion or part of the population of interest.
7) To infer something about a population, we usually take a sample from the population.
8) Descriptive statistics are used to find out something about a population based on a sample.
9) There are four levels of measurement: qualitative, quantitative, discrete, and continuous.
10) The ordinal level of measurement is considered the "lowest" level of measurement.
11) A store asks shoppers for their zip codes to identify market areas. Zip codes are an example
of ratio data.
12) An ordinal level of measurement implies some sort of ranking.
13) Data measured on a nominal scale can only be classified into categories.
14) The terms descriptive statistics and inferential statistics can be used interchangeably.
15) A marketing research agency was hired to test a new DVD player. Consumers rated it
outstanding, very good, fair, or poor. The level of measurement for this experiment is ordinal.
16) The Union of Electrical Workers of America with 9,128 members polled 362 members about
a new wage package that will be submitted to management. The population is the 362 members.
17) The CIA World Factbook cited these numbers for the United States:
• The birthrate is 13.66 births per 1,000 of the population.
• The average life expectancy for females is 81.17 years.
• Approximately 316.7 million persons reside in the United States.
Each of these numbers is referred to as a statistic.

,18) If we select 100 persons from 25,000 registered voters and question them about candidates
and issues, the 100 persons are referred to as the population.
19) Statistics is defined as a body of techniques used to facilitate the collection, organization,
presentation, analysis, and interpretation of information for the purpose of making better
decisions.
20) Categorizing voters as Democrats, Republicans, and Independents is an example of interval
level measurement.
21) The order in which runners finish in a race would be an example of continuous data.
22) Based on a sample of 3,000 people, the civilian unemployment rate in the United States was
5.5%. 5.5% is referred to as a statistic.
23) The principal difference between the interval and ratio scale is that the ratio scale has a
meaningful zero point.
24) The branch of mathematics used to facilitate the collection, organization, presentation,
analysis, and interpretation of numerical information is referred to as statistics.
25) The number of children in a family is a discrete variable.
26) The main purpose of descriptive statistics is to
A) summarize data in a useful and informative manner.
B) make inferences about a population.
C) determine if the data adequately represent the population.
D) gather or collect data.
27) Which of the following is an example of a continuous variable?

C) Interval
D) Ratio
31) A portion or part of a population is called a
A) random survey.
B) sample.
C) tally.
D) frequency distribution.
32) If Gallup, Harris, and other pollsters asked people to indicate their political party affiliations
as Democrat, Republican, or independent, the data gathered would be an example of which scale
of measurement?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
33) The members of each basketball team wear numbers on their jerseys. What scale of
measurement are these numbers considered?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
34) A marketing class of 50 students evaluated the instructor using the following scale: superior,
good, average, poor, or inferior. The descriptive summary showed the following survey results:
2% superior, 8% good, 45% average, 45% poor, and 0% inferior.
