Quantative Analysis Principles

understanding of the basic principles of quantitative analysis,

as these principles are relevant to educational research. Two ì

objectives of this paper are to demonstrate an understanding of

the material presented in the text, and to discuss how the

concepts and principles may be applied in practice.ì

Principles of Quantitative Analysisì

In scientific inquiry, a proposition is a statement "about ì

concepts which may be judged as true or false if it refers to ì

observable phenomena. When a proposition is formulated for ì

empirical testing we call it a hypothesis."  3.ls1

declarative statements that are both tentative and conjectural in ì

character. Hypotheses may be both descriptive and relational in ì

Theory, in scientific inquiry, is, in effect, a descriptive ì

explanation of how something works--an explanation of the ì

interrelated actions within a system. While hypotheses may be ì

The validity of this measuring ì ì instrument calibrated in feet and inches would be determined on ì ì the basis of its ability to accurately measure feet and inches in ì ì accordance with an external standard, such as a master ì ì measurement instrument maintained by the National Bureau of ì ì Standards. An instrument designed to measure some psychological ì ì characteristic or factor would have to be evaluated in the ì ì context of validity on the basis of its ability to yield results ì ì consistent with those of another instrument whose validity has ì ì previously been established. Thus, if an instrument were ì ì designed to provide a measurement of a tendency toward abnormal ì ì behavior, the measurements provided by the instrument would have ì  = . á2
