Review of the Statistical Techniques in Medical Sciences

UM Okeh, AC Ugwu

Abstract




Medical scientists often times are faced with the need to choose the right statistical technique for a given set of data. There are a number of criteria that should be a guide in making the right choice: the research questions, the category of the variables involved the size of the sample, the scale of measurement of the variable, the type of study design, among others. This article reviews some procedures which will be followed by any medical researcher in selecting the appropriate statistical techniques. Of course, all statistical techniques have certain underlying assumptions, which must be checked before the technique is applied.

Keywords: Variable, Prospective Studies, Retrospective Studies, Statistical significance
