Terminology Review
Chapter 3CCha
Each of the players is a thinking, rational entity
seeking to maximize his or her share of the booty. The term
that describes this is
Rationality
The players are willing participants and accept the rules of the game as
binding. This is called
Cooperation
This method can be used anytime the fair-division
game involves two players and a continuous set S (a
cake, a pizza, a plot of land, etc.)
Divider-Chooser Method
When the booty “S” is divided among N players
and each player’s portion is worth at least 1/N th of the total value
in the opinion of the players, we call that
A Fair Share
If there are more than 2 players, the division
method is called
The Lone Divider method
When players write what they consider a
fair share on a piece of paper this is called
Bidding
When decisions are made as to who gets
what share this is called.
Distribution
When property is divided among several
people, where each person can be a buyer
and a seller, the method used is called .
Sealed Bids
When each item in a property division goes to the highest bidder,
this is called.
Allocation
In Sealed bids, the difference of the value of the item each player gets and the player’s
fair-share is called the..
First Settlement
After each player has paid what is owed in a sealed bid process, if there is money left
over, it is called
The surplus
When the surplus is added to the First
Settlement , the result is called .
The Final Settlement
Chapter 5.
The combination of a set of dots and lines connecting them is
called.
A Graph
Each dot in a graph is called
A Vertex
A Line connecting two vertices is called
An Edge
If two vertices in a graph are joined by an edge they
are..
Adjacent
The name for the number of edges
meeting at a vertex is called a
Degree
If a vertex has 4 edges connecting to it is an
Even Vertex
If a vertex has 3 edges connecting to it is an
Odd Vertex
A closed trip through a graph is called a
Circuit
An open trip through a graph is called a
Path
If you can get from any vertex to any other vertex along a path the
graph is
Connected
A graph that is composed of separate
components is ..
Disconnected
If a graph is connected and every vertex is even then it has
A Euler Circuit
If a graph is connected and has exactly two
odd vertices then it has
A Euler Path

Data presented in this format is called
Data presented in this format is called..
A Bar Chart
A Group of data is called
A Data Set
Each individual data point is called
A Data Value
When the difference between data values of a numerical value can
be made arbitrarily small it is called
A Continuous Variable
When possible values of a numerical variable
change by minimum increments it is called
A discrete variable
When a numerical variable is continuous
it is usually represented by a
variation of a bar chart that is called
A Histogram
In Statistics another word for “Average” is
Mean
The middle value of a data set is called
The Median
If a certain percent of the numbers in a data set fall below a certain value and the rest fall above it the term used
to describe this is
Percentile
A variable that represents a
measurable quantity is called
A quantitative variable
Variables that represent
characteristics that that cannot be
measured numerically are called
Qualitative Variables
The difference between the highest and lowest
value in a data set is called
The Range
The average of the squared differences
between the mean and each data value is
called
The Variance
The Square root of the variance is called
The Standard Deviation
Chapter 13
Every statistical statement refers
directly or indirectly to some group of
individuals or objects. This group is called
The Population
The process of collecting data by
going through every member of a population
is called
A Census
When collecting data from only some members of the
population the process is called
A Survey
A survey in which members of a sample
provide information by answering specific questions from an
interviewer is called
A Poll
When we survey only some members of the
population, the resulting group is
called
A Sample
When the choice of a sample has a built-in tendency to exclude a
particular group or characteristic we call
that
Selection Bias
The Percentage of respondents out of the total sample is called
The Response Rate
When the response rate to a survey is low, the survey is said to
suffer from
Nonresponse bias
When the survey uses a systematic effort to
force the sample to be representative of a
given population, this is called
Quota Sampling
A Sampling method that uses randomness as part of its design is
know as
Random Sampling
The term used to indicate data obtained from a sample is called
A Statistic
A Statistic is always an estimate of an
unknown measure of the population. This
measure is called
A Parameter
In surveys or polls, when the sampling
frame is broken down into categories this is
called
Stratified Sampling
