Concepts and variables are mental images; concepts are highly subjective and cannot be measured unless they are operationalized while variables can be measured on one of the statistical scales. to understand concepts and variables let’s read about them in detail. What are concepts? Concepts are highly subjective in nature and that makes it difficult to use them as they are …

The interval scale has all the properties of ordinal and nominal scale plus the benefit that it provides equal intervals among categories. The values in the interval scale can take positive or negative values. This property enables the use of statistical analysis on data measured using interval scale. Age, IQ, temperature and dates are few examples of an interval scale. …

The ordinal scale ranks the individuals, responses or objects into sub-categories and it also makes it possible to rank these sub-categories into some order of magnitude. This property of ordinal scale, to rank objects in some order, makes it different from the nominal scale.  It does not quantify “how much” different in magnitude each sub-category is from the other. For …

There are basically four measurement scales in statistics that are used to categorize the variables under study. These four measurement scales include; nominal, ordinal, interval and ratio scales.  In physical science, the measurement needs to be very accurate and precise but in social science, the measurement cannot be as accurate and it is a lot more subjective. The measurement scale …

What are variables in research? This is an important question that students should know before attempting to formulate a research problem. In general terms, variables are concepts that can be measured and operationalized. In the research, there are concepts that the researcher deals with these concepts are highly subjective, for example, some concepts about a community health program. There will …
