Tabulation is a systematic and logical representation of numeric data in rows and columns to facilitate comparison and statistical analysis. It facilitates comparison by bringing related information close to each other and helps in statistical analysis and interpretation. In other words, the method of placing organised data into a tabular form. Tabulation essentially bridges the gap between the collection of data and analysing them. The primary objectives of tabulation can be encapsulated below -. For Simplification of Complex Data -. When any information is tabulated, the volume of raw data is compressed and presented in a much more simplified manner Classification of data meaning, tagging data so that it can be easily tracked. Moreover, it eliminates duplicate data which frees up storage space, lowers backup cost, and accelerates the search process. Types of Data Classification.

Classification of Data. The process of arranging data into homogenous groups or classes according to some common characteristics present in the data is called classification. For example: During the process of sorting letters in a post office, the letters are classified according to the cities and further arranged according to streets Data Analysis and Compilation. After gathering the information from desk and field research the raw data must be compiled so that the taxonomic analysis can be performed and data can be broken up into respective parts and segments. This can be achieved in the following manner: 1. Keeping on revisiting and focusing on the ultimate objective of.


This procedure is referred to as tabulation. Thus, tabulation is the process of summarising raw data and displaying the same in compact form (i.e., in the form of statistical tables) for further analysis. In a broader sense, tabulation is an orderly arrangement of data in columns and rows. Tabulation is essential because of the following reasons Chief, Classifications and Public Health Data Standards. Head, Collaborating Center for the WHO -FIC in North America Multi-purpose and coherent classification - Mortality, morbidity, primary care, clinical care, research, public - Multiple classifications and tabulation lists can be derived from the foundatio Data classification tags data according to its type, sensitivity, and value to the organization if altered, stolen, or destroyed. It helps an organization understand the value of its data, determine whether the data is at risk, and implement controls to mitigate risks. Data classification also helps an organization comply with relevant industry. A scientific investigation adopts a certain sequential procedure, an organized plan or a research design to collect and analyze data about the problem under study. In general, this plan includes some scientific steps: formulation of hypotheses, compilation of facts, analysis of facts (classification, coding and tabulation) and generalization. Many meaningful results pertinent to workforce analysis can be produced through tabulation of population-based data. All countries collect at least some data on their population, mainly in terms of periodical demographic censuses and household sample surveys that produce statistical information abou

interpretation. These methods are applied on the data collected for the purpose of decision making in various fields of scientific inquiry.

After comprehensive tabulation of symptom classifications from the International Classification of Diseases (ICD-9), we performed a survey of nonmedical laypersons. Data analysis included descriptive statistics, proportional calculations, and 95% confidence intervals project. The soils survey, testing and classification of materials must be performed by a qualified geotechnical laboratory. The plans will include the information about the soil classification on the soil survey sheet and by showing the boring data soil boxes on the cross section sheets Data coding in research methodology is a preliminary step to analyzing data. The data that is obtained from surveys, experiments or secondary sources are in raw form. This data needs to be refined and organized to evaluate and draw conclusions. Data coding is not an easy job and the person or persons involved in data coding must have knowledge. Types of Variables Based on the Types of Data. A data is referred to as the information and statistics gathered for analysis of a research topic. Data is broadly divided into two categories, such as: Quantitative/Numerical data is associated with the aspects of measurement, quantity, and extent. Categorial data is associated with groupings

Adam Smith (1723 -90) defined economics as follows : 'Economics is the science of wealth'. He is the author of the famous book 'Wealth of Nations' (1776).
