It makes data easier to understand also has a lot more advantages like this. 5. It is the series of steps for extracting information from raw data. Data collection is a very important step in processing where all raw facts are collected from various environments which should be well defined and accurate to processes it. Tabulation i.e. You can skip testing the hypothesis and base the analysis on frequency tables and cross-tabulations only. ... Cross-tabulation is one technique for measuring association and control - ling other variables and is introduced in this chapter. The large mass of confusing data is easily reduced to reasonable form, that is understandable to kind. 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. Like for example manually writing or calculating a report manually and accurately is manual processing, manually verifying marks sheet, financial calculation, etc. Rules of Tabulation. It makes data easier to understand also has a lot more advantages like this. For example, an instruction to order the … The three main forms of presentation of data are: 1. The mass of data is presented in a concise and simple manner by means of statistical tables. Analysis of data began immediately and continued to as long as the project was active. Tables are useful for data with specific amounts rather than approximations. The word data comes from the Latin language, which means the collection of raw information. Rare article on internet but you write it very well and this is very informative. 3. The various disadvantages of data analytics are as follows: Data analytics can breach customer privacy as information such as online transactions, purchases, or subscriptions, can be viewed by the parent companies. It is a continuous process, which responds within seconds when the data input is given it gets processed and provides desired output data. It facilitates comparison by bringing related information close to each other and helps in further statistical analysis and interpretation. Use in the Notice Board: Such representation can be hanged in the notice board to quickly raise the attention of employees in any organization. Fundamentally, it measures how different variables are related to each other. Disadvantages of simple bar charts (2) cant do it with continuous data, width of bar can mislead true value. Tabulation is a very cheap mode to present the data. At this stage, the data output which is obtained after processing is meaningful data, that is required for end-users. In a logistic tracking area, this processing helps in retrieving the required customer data online. For example, If we purchase an item in a departmental store they provide us bill after purchasing, where the bill contains all the data items information like item details, customer name, phone number, address, time, bill amount, amount paid, tax, etc, all these put together forms an information, where this information is process form of data. There are no hard and fast rules for preparing a statistical table. A line graph plots data points along a number line. 1.3.2.2 1.4 PIE CHARTS A pie chart or circular diagram is one which essentially displays the relative figures (proportions or percentages) of classes or strata of a given sample or population. Presentation of data is of utter importance nowadays. - Structure & Tuning Methods. The process of converting raw facts into a form that is easier to provide as an input to the processing system is data encoding. Tabulated data can be easily understand and interpreted. 4.
