First, second, third, fourth... What kind of data does this represent?
a) continuous data
b) nominal data
c) discrete data
d) ordinal data
Ordinal data places data objects into an order according to some quality.
This kind of data is also called categorical data.
a) continuous data
b) nominal data
c) discrete data
d) ordinal data
Nominal data is used to put data into categories, which is why it is also known as categorical data.
Assume you are measuring the various lengths of used pencils, and you collect the following data points
(in inches): 1.37, 2.65, 2.78, 3.46, 3.91. What kind of data are these data points?
a) continuous data
b) nominal data
c) discrete data
d) ordinal data
In a set of continuous data, a point can lay along any point in a range of data.
,A data point that can only take on whole values and has boundaries is called what?
a) continuous
b) nominal
c) discrete
d) ordinal
Discrete data points are always whole integers.
If a measure is consistent and repeatable it is said to be .
a) good
b) correct
c) valid
d) reliable
To be considered reliable, a measure must be repeatable in multiple locations under diverse conditions.
A small group from which you make an inference about an entire population is called a .
a) sample
b) representation
c) model
d) medium
If chosen properly, a sample can make predictions about an entire population.
Cleaning and organizing data that has been collected is known as .
a) data cleanup
b) data entry
c) data management
d) data mining
Managing your data is as important as your analysis.
From data mining, someone is able to make conclusions about the underlying causes of certain variables.
True
False
This is a false statement. Data mining is often able to find trends, but it will usually overlook the
underlying causes.
As technology improves, there will be a greater amount of raw data.
True
False
This statement is true. Data collection will become easier as technology improves which will lead to an
increase in raw data.
,The first step in the Davenport-Kim three-stage model is to frame the problem by recognizing what the
problem is and then reviewing previous findings to begin to structure the analysis.
a. True
b. False
Stage #1 is to frame the problem by recognizing what the problem is and then reviewing previous
findings to begin to structure the analysis. Stage #2 is to solve the problem. Stage #3 is to communicate
your findings.
The stage that involves the most intense statistics and data work is stage 3, communicating results.
a. True
b. False
The stage that involves the most intense statistics and data work is stage 2, solving the problem. This
step includes data modeling, data collection, and data analysis.
The following are examples of nominal data:
male/female red/blue living/deceased
True
False
Nominal data, sometimes called categorical data, places objects into a category.
Interval data has an order and all the objects are an equal interval apart.
True
False
This statement is true. Interval data has an order and all the objects are an equal interval apart. You
cannot have a natural zero point in interval data.
Interval data and ratio data are both types of continuous data.
a. True
b. False
This is a true statement. Interval data and ratio data can take any value on a given interval, which means
they are types of continuous data.
College major is an example of ordinal data.
a. True
b. False
This is a false statement. Ordinal data places data objects into an order according to some quality.
College majors do not have an inherent ordering, so they are not an example of ordinal data.
Observational studies are often used when a surveyor wants to adjust different variables and take note
of the effects.
True
False
, This statement is false. Observational studies are used when it is impractical or impossible to control the
conditions of the experiment.
Data is valid if it can be repeated by the same person in the same lab each and every time the
experiment is executed.
True
False
This statement is false. Data is only valid if the experiments can be executed by more than one individual
in different locations (not necessarily different conditions as that could be part of the experiment).
It is ethical to report only results which match your expectations without citing those which do not
conform to your expectations.
a. True
b. False
This is a false statement. You should provide some reasoning for not including any results which are not
reported or cited, even if they go against your expectations of the data.
Transparency of methods used and any assumptions made is a step towards an ethical statistical study.
a. True
b. False
This is a true statement. An ethical study will include information about the methods used and what
assumptions are made throughout the analysis.
Which of the following is not a guideline for an ethical statistical study?
a. If you are not qualified for work, you should consult with someone who is qualified.
b. You do not need to acknowledge employed statisticians in published reports.
c. You should include any limitations or sources of error in your study.
d. You should obtain approval to use research subject data before using it for other studies.
**To maintain an ethical study, you must acknowledge the work of your employed statisticians for their
contributions in all relevant reports.
If you were to take your temperature 10 times in a row using the same thermometer and got the same
result every time, you could say that the thermometer is .
a) valid
b) reliable
c) accurate
d) measurable
Feedback: The correct answer is B. A test is reliable if it is consistent and repeatable.
According to the 2000 census the average number of people in a family in the U.S. was 3.17. Since it isn't
possible to have .17 of a person, you would use a data point to describe the number of
people in your family.
