ConceptualizationIt is a process

of communicating concepts about external realities.

Concepts as Constructors

Three classes of phenomena which can be statistically measured:

Direct observables

Indirect observables

Mind-constructs

LOVE

COMPASSION

Indicator And Dimension Dimensionis a specific aspect of a concept combined into groups or sub-groups

Indicatoris a sign of the presence of a concept (variable) under study

Visiting a home for the aged Allocating donation for

charitiesGiving help to street children

Human Compassion

Creating Conceptual Order

CategorizationA process of ordering or ranking of data.

SpecificationA process of making concepts clear

Conceptualization

Nominal Definition

Real Definition

Operational Definition

Conceptualization-specifying what we mean

Nominal Definition-assigning to a term(not the real entity)

Real Definition-specifying how a concept is measured

Operational Definition-clarified status of a real thing

OperationalizationIt is a process

of selecting observable phenomena to represent abstract concepts.

Attributes may represent any of the four levels of measurement

Variables and Attributes

AttributeQuality or characteristics of something

VariableLogical set of attributes

-any property that varies-several possible values

-only two possible values

LEVELS OF MEASUREMENTNominal MeasureOrdinal MeasureInterval MeasureRatio Measure

Nominal Measuredescribing a variable that has attributes which are

different

Ordinal Measuredescribing a variable with attributes that can be in

a rank-order along some dimension

Interval Measuredescribing a variable whose attributes are rank-ordered and have equal distances between adjacent attributes

Ratio Measuredescribing a variable with attributes that have all the qualities of nominal, ordinal and interval and

based on a ”true zero” point
