Statement:Statement: is an important basic element in any is an important basic element in any attempt to build a scientific body of attempt to build a scientific body of knowledge.knowledge.

Analysis:Analysis: is one approach to theory building.is one approach to theory building.In analysis one clarifies ,refine and In analysis one clarifies ,refine and sharpens concept, statement, and sharpens concept, statement, and theory.theory.

Definition:

It is a process of examining It is a process of examining statements to determine if the statements to determine if the

statement is useful, informative, and statement is useful, informative, and logically correct.logically correct.

So what is statement analysis?

Rational Statement:Rational Statement: Each statement describes some type of Each statement describes some type of

relationship between or within the relationship between or within the concepts of the statement. It is the concepts of the statement. It is the

skeleton of theoryskeleton of theory

Non rational Statement :Non rational Statement : It is the theoretical and abstract It is the theoretical and abstract definition of the concepts at the definition of the concepts at the statement. It is the way by which the statement. It is the way by which the theorist clarifies the meanings in the theorist clarifies the meanings in the theory. theory.

Definition/Abstract

Descriptive Definition :

Describe the accepted

Stipulative Definition :

Describe the term that has a scientific use

within the theory.

Operational Definition :

includes the specific means for measuring or testing

Simplify the statementSimplify the statement

•Simplifying the statement is needed Simplifying the statement is needed for 2 reasonsfor 2 reasons::

•The problem of elaborative verbal The problem of elaborative verbal concepts must be must be reduced concepts must be must be reduced

to manageable statementsto manageable statements..•The second problem is complexity The second problem is complexity

where one concept may be linked to where one concept may be linked to several others simultaneouslyseveral others simultaneously

Stipulative DefinitionStipulative Definition

•It is specifically formulated only for It is specifically formulated only for use in the way the author or use in the way the author or

researcher has decreed. For example researcher has decreed. For example ‘ for the purpose of this study a ‘ for the purpose of this study a

kitten shall be defined as any kitten shall be defined as any healthy female offspring of a healthyhealthy female offspring of a healthy

female cat that is less than 8 weeks female cat that is less than 8 weeks oldold..

Operational DefinitionOperational Definition

•Includes the specific means for measuring Includes the specific means for measuring or testing each scientific term within itor testing each scientific term within it. .

•An operational definition must be precise An operational definition must be precise so that if it is used repetitively it will give so that if it is used repetitively it will give

an objective results. For example ‘ For the an objective results. For example ‘ For the purpose of the study a kitten any healthy purpose of the study a kitten any healthy

female offspring of a healthy female cat female offspring of a healthy female cat weighing between 4 and 12 ounces and no weighing between 4 and 12 ounces and no less than 3 days or more than 12 days oldless than 3 days or more than 12 days old..
