What is the Classification of data in Statistics?
For performing statistical analysis, various kinds of data are gathered by the investigator or analyst. The information gathered is usually in raw form which is difficult to analyze. To make the analysis meaningful and easy, the raw data is converted or classified into different categories based on their characteristics. This grouping of data into different categories or classes with similar or homogeneous characteristics is known as the Classification of Data. Each division or class of the gathered data is known as a Class. The different basis of classification of statistical information are Geographical, Chronological, Qualitative (Simple and Manifold), and Quantitative or Numerical. For example, if an investigator wants to determine the poverty level of a state, he/she can do so by gathering the information of people of that state and then classifying them on the basis of their income, education, etc.
How to Calculate Range of Data?
Range of Data calculator uses Range of Data = Largest Item in Data-Smallest Item in Data to calculate the Range of Data, Range of Data formula is defined as the difference between the maximum and minimum values in a dataset, and calculated using the largest and smallest items in the data. Range of Data is denoted by R symbol.
How to calculate Range of Data using this online calculator? To use this online calculator for Range of Data, enter Largest Item in Data (Max) & Smallest Item in Data (Min) and hit the calculate button. Here is how the Range of Data calculation can be explained with given input values -> 60 = 85-5.
