Validity In Quantitative Content Analysis

VALIDITY IN QUANTITATIVE CONTENT ANALYSIS (QCA QCA has been be as a a query proficiency for the domineering objective , and quantitative of the manifest guinea pig of communication (Berelson , 1952 . The technique involves the process of segregating communication content into different units , assigning each unit to a singular category and providing quantitative enumeration to each category . Networked computers are now being utilise in education to facilitate communication theory and hence QCA arse also be effectively utilize for content outline in the resembling . The use of QCA to educational applications in communications which are mediated by computers however needs to be bindingatedQCA as a form of examination and measurement is a powerful tool but can be used only after procedures for test development have been effectively codified . Studies on use of QCA indicated that the conclusions used such as frequency of posting messages on computer networks and average occur of words used did not support the need for a systematic measurement These are particularly difficult in analyzing inferences that can be drawn from content which is a juncture of assessing knowledge transformations . For this purpose well designed tests need to be effectively formalized Coding protocols which are theoretic 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 behaviors that represent the construct , reviewing the categories and indicators , having preliminary tryouts and in the end developing guide lines for administration , scoring and interpretation of the label scheme . It is only after going through all these steps that a valid instrument will be available to the content analyst Finally the empirical grounds gathered needs to be evaluated for validity 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 felt 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 .
