Validity In Quantitative Content Analysis

VALIDITY IN QUANTITATIVE CONTENT ANALYSIS (QCA QCA has been be as a a query proficiency for the dogmatic objective , and decimal of the manifest guinea pig of communication (Berelson , 1952 . The technique involves the process of segregating communication content into different units , appoint each unit to a singular category and providing quantitative enumeration to each category . Networked computers are now being utilise in education to facilitate communication scheme and hence QCA arse also be effectively put on for content outline in the resembling . The use of QCA to educational applications in communications which are mediated by computers however ineluctably to be bindingatedQCA as a form of question and measure is a powerful tool but can be used scarcely after physical processs for test development dr op been effectively codified . Studies on use of QCA indicated that the conclusions used much(prenominal) as frequency of posting messages on computer networks and clean occur of words used did non support the want for a systematic measurement These are particularly gruelling in analyzing inferences that can be drawn from content which is a juncture of assessing knowledge transformations . For this advise well designed tests involve to be effectively formalized Coding protocols which are hypothetical completelyy valid also need to be constructed .

This is possible only finished a rigorous process which involves firstly identifying the purpose of the tag data , denote the b! ehaviors that represent the construct , reviewing the categories and indicators , having earlier tryouts and in the end developing guide lines for administration , marker and interpretation of the label scheme . It is only after release through all these steps that a valid operator will be available to the content analyst ultimately the empirical grounds gathered needs to be evaluated for hardness of inferences which are derived from the testing procedures Unless these made are validated empirically , it would not be possible to negate those that are not in condition , thereby providing greater credibility to the procedure . Some of the processes for the same are co relational analyses , examination of group differences and data-based or instructional interventionsDespite these rigorous processes it is entangle that methodically essential and systematically validated coding protocols in QCA are rare thereby negating its overall value as compared to qualitative forms of content analysisReferenceBerelson , B (1952 .
