Is the science of the development of applications of the most effective methods for planning experiments, obtaining data, and then analyzing, interpreting, and drawing conclusions based on the data.

Is branch of mathematics that deals with uncertainty. It is a measure or estimation of how likely it is that an event will occur.

An attribute that describes a person, place, thing, or idea. It is a characteristic that is observable or measurable in every unit of universe.

The process of gathering and measuring information on variables of interest,

in an established systematic fashion that enables one to answer stated research questions,

test hypotheses, and evaluate outcomes.

A _____ is any specific collection of objects of interest.

A _____ is any subset or subcollection of the population, including the case that the sample consists of the whole population, in which case it is termed a census.

A _____ is any subset or subcollection of the population, including the case that the sample consists of the whole population, in which case it is termed a census.

Is a number or attribute computed for each member of a population or of asample. The _____ of sample elements are collectively called the sample data.

A _____ is a number that summarizes some aspect of the population.

Is the branch of statistics that involves organizing, displaying, and

describing data.

Is the branch of statistics that involves drawing conclusions about a

population based on information contained in a sample taken from that population.

are measurements for which there is no natural numerical scale, but which

consist of attributes, labels, or other nonnumerical characteristics.

Are numerical measurements that arise from a natural numerical scale.

A variable which can assume finite, or at most countably infinite number of values; usually measured by counting or enumeration; data that can be counted

Avariable which can assume infinitely many values corresponding to a line

interval; values are obtained by measuring.

(LEVELS OF DATA MEASUREMENT AND SCALES)

- of measurement arises when we have variables that are categorical and non-

numeric or where the numbers have no sense of ordering.

(LEVELS OF DATA MEASUREMENT AND SCALES)

- also deals with categorical variables like the nominal level, but in this level

ordering is important, that is the values of the variable could be ranked.

(LEVELS OF DATA MEASUREMENT AND SCALES)

- a measurement scale that, in addition to ordering scores from highest to lowest, the difference between data points can be quantified.

(LEVELS OF DATA MEASUREMENT AND SCALES)

- also tells us that one unit has so many times as much of the property as does another unit.
