There are three different types of data manipulating techniques they are. Decision Making: Business executives can view the graphs at a glance and can make a decision very quickly which is hardly possible through the descriptive reports. Depending upon the number of variables and data analysis methods used, primary data analysis cannot be fit in less than 3000 words. Examples of data collection are land surveys, election polling. Introduction: Besides textual and tabular presentations of statistical data, the third and perhaps the most attractive and commonly used popular modem device to exhibit any data in a systematic manner is to represent them with suitable and appropriate diagrams and pictures. The activities carried out in data input are of four stages, they are. Data classification is the process of organizing data into categories that make it is easy to retrieve, sort and store for future use.. A well-planned data classification system makes essential data easy to find and retrieve. It facilitates comparison by bringing related information close to each other and helps in further statistical analysis and interpretation. Acceptability: Such a report is acceptable to busy persons because it easily highlights the theme of the report. Hadoop is the most commonly used tool for Big Data analytics. In-depth analysis can take many forms from complex tabulations, multivariate analyses or by giving users of the survey data access to the data for re-analysis. Disadvantages of direct tabulation of administrative data. Errors and Mistakes: Since graphical representations are complex, there is- each and every chance of errors and mistakes.
