TECHNIQUES FOR INTERPRETING THE RESULTS OF FACTOR ANALYSIS IN RESEARCH WORK
Main Article Content
Abstract
Factor analysis is a statistical technique applying for reducing the number of variables when there are bunches of variables involved. This can be done by grouping the related variables under the condition that the relationship of those being grouped must be at a high level in either the same (positive) or different (negative) direction. The entire groups must have no or very low level of relationship. The preliminary conditions for this application are that: the number of selected variables should greater than 20; and the sample size must be 5 or 6 six times of the number of variables concerned. Therefore, this technique enables the researcher to interpret the meaning of each variable easier, more accurate and more reliable.
