Normalization Transformations of Data in the Procedure of Statistical Methods Used in Education Research

Introduction : Sometimes the mapping of variable values made during measurement needs to be transformed due conditions related data analysis. Research Aim The aim this article is present issue normalization transformation and circumstances their application. Evidence-based Facts Due lack knowledge or experience, transformations are not taken into account in analysis education research. And if they do occur, among most popular methods transformation, chosen those which reduce skewness distributions. However, method always adequately properties Normalization simpler yet effective solutions for preparing Summary minimize risk artifacts differences orders magnitude units measurement. This particularly important when conducting analyses using multidimensional scaling multivariate classification methods.
