The methodologist scholars have classified researches in to two general groups:
1- quantitative researches and 2-qualitative researches. This article is aimed at considering the qualitative researches. Therefore, first important characteristic of qualitative researches and the improtant differences of such researches and quantative ones are studied. Then some examples of qualitative researches are discussed, and their major implementations are presented. The results of this study are as follows:
1-The qualitative researches do not stand in a lower rank than quantitative researches from the importance point of view and the scientific structure of research.
2-The choice between a quantitative or qualitative research depends on numerous factors. The most important determinant structure is the nature of the subject, the problem under study and the experience of the researcher.
3-Some of the kinds of quantitative research methods (as an example, the case and ground research) can present deep and accurate information about phenomena and complicated organizations. Obtaining such information through quantitative researches is not possible.
4-In most cases both kinds of quantitative and qualitative techniques can be used to increase internal and external feasibility t.e. the quantitative and qualitative research methods can complete each other.
It is Auggested that quantitative research techniques and methods should be written more practical and more complete to strengthen their internal and external feasibility, and the credibility of such researches should increase in future.
