Abstract: This paper seeks to explain the scale of measurement and the transformation of the ordinal scale to distance scale by using the Method of Successive Interval (MSI). In addition, in this paper demonstrated a statistical difference in the groups of test results before the data transformation and after transformation by using MSI. Using statistical tests on group data before and after transformation raises interpretation distinction. Oversight in selecting statistical test will lead to wrong interpretation as well. Therefore, it is required accuracy in selecting test statistic in a study. Data obtained from measurements using an ordinal scale should be tested with a non-parametric statistics. However, if you want to use parametric statistics, the transformation of the ordinal scale to scale the distance (interval) should be done first.
Keywords: measurement, transformation, ordinal, interval, successive.
