Every variable in a research study that is assigned a specific number must be similar to every other variable assigned to that number what is levels of measurement the categorization of the precision with which an event can be measured. This process is referred to as measurement the variables that are measured are commonly classified as being measured on a nominal, ordinal, interval or ratio scale .

Interval and ratio variables together are often called numerical variables because they provide a number which measures `quantity' (how much, how many) of something nominal and ordinal variables together are often called categorical variables because they classify into categories rather then count or measure. Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events the scope and application of measurement are dependent on the context and discipline. Measurement is the process of systematically assigning numbers to objects and their properties to facilitate the use of mathematics in studying and describing objects and their relationships. The process is not about arbitrary units or scales, but the actual type of measurement it must take into account both the nature of the variables , and the type of data generated by the research method .
Measurement is the process of determining the existence, characteristics, size, and/or quantity of changes in a variable through systematic recording and organization of the researcher’s observations. The measurement scales, commonly used in marketing research, can be divided into two groups comparative and non-comparative scales comparative scales involve the respondent in signaling where there is a difference between two or more producers, services, brands or other stimuli.
