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
