Kajian Metode Suksesif Interval (MSI) dalam Mengubah Data Ordinal Menjadi Data Interval dan Dampaknya terhadap Distribusi

Abstract

Interval successive method is a method that can change the ordinal data into interval data . In a variety of statistical testing process , the data used must be interval scale , therefore , if the data held by investigators ordinal scale it must first be converted into the form of a scale interval . Descriptive statistics are used to see the difference of condition data between the data ordinal scale with interval scale data . Scatterplot is used to see the pattern of dissemination of data and comparing the pattern of dissemination of data between the data ordinal scale with interval scale data . Manual calculations of the method of successive intervals carried out to clarify the process of transformation of the data originally ordinal scale into an interval scale data
