Abstract :One of modern practical theology’s task is what so-called descriptive-empirical task. In this sense practical theology does require an empirical approach for her reflection. Therefore practical theologians should have sufficient skills in using methods of field research. Traditionally qualitative methods have been known more among theologians. And in the same time some people suspect that quantitative methods are not suitable and cannot explain any theological problems. Some others concern and think that quantitative methods only work deductively and it is against the tradition of theology from below which normally works inductively. This essay would like to show how quantitative methods can work within theological field and give theologians an alternative approach when they want to empirically understand particular religious community. Obviously we realise that social sciences such as sociology and social psychology have developed quantitative methods in their researches for long time. In the spirit of interdisciplinary approach we owe them some explanations in running particular quantitative analyses.
