ABSTRACT
This article presents an overview of the measurement scales and their summary statistics. In any study, observations are made on each individual. These observations vary both between and within individuals and are thus referred to as variables. One can summarize the data collected in a study either numerically, in the form of summary statistics, or in tabular or graphical form. The advantage of the first method is that individual statistics can be used to summarize the data simply; on the other hand all, or most, of the data can be presented in a table or figure. The appropriate summary method depends on the type of variable and its measurement scale.
