Steps Involved in Processing of Data
STEPS INVOLVED IN PROCESSING OF DATA IN RESEARCH METHODOLOGY
Introduction After the collection of the data has been done, it has to be then processed and then finally analyzed. The processing of the data involves editing, coding, classifying, tabulating and after all this analyzation of the data takes place.
Data Processing The various aspects of the data processing can be studied as follows
1. Editing of data: – This aspect plays a very vital role in the detection of the errors and omissions and then helps to correct these errors by which ,the degree of accuracy, consistency and homogeneity are increased. By this method, coding and tabulation of the data is done and also scrutiny in a very careful manner of the completed questionnaires takes place.
Editing of the data can be done in the following two stages:-
• Field Editing – In this step, the reporting firms are reviewed by the investigator and then the translation of what the latter has noted in the abbreviated form takes place. • Central Editing -. In this type of editing, edition of all the forms is done carefully and thoroughly by a single person only in a small study and by a small group of persons in case of a large study. 2. Coding of Data: – This step involves assignment of some symbols, either alphabetical or numerals or both, to the answers.By doing this coding of the data, analysation of the data can be performed in a much efficient manner but a very vital point to be kept in mind here is that there should be no errors while assigning the codes or should be at the minimum possible level. 3. Classification of Data: – The step of classification in general terms can be defined as the arrangement of the data into groups and classes depending on the resemblance and the similarities. With the help of the classification of the data, the entire data can be condensed; with this important characteristics can be very easily noticed. The various features of the variables can be
