Unformatted text preview: iables or later analytical modification requirements could be easily incorporated into the data sets. The editing step checks for the completeness, accuracy and uniformity of the data set created by the researcher. The edited data are then subject to codification and classification. Coding process assigns numerals or other symbols to the several responses of the data set. It is therefore a pre-requisite to prepare a coding scheme for the data set. The recording of the data is done on the basis of this coding scheme. Numeric Coding: Coding need not necessarily be numeric. It can also be alphabetic. Coding has to be compulsorily numeric, when the variable is subject to further parametric analysis. Alphabetic Coding: A mere tabulation or frequency count or graphical representation of the variable may be given an alphabetic coding. Zero Coding: A coding of zero has to be assigned carefully to a variable. The transcription of data can be used to summarize and arrange the data in compact form for further analysis. Computerized tabulation is easy with the help of software packages. Frequency tables provide a “shorthand” summary of data. The importance of presenting statistical data in tabular form needs no emphasis. The major components of a table are: o A Heading: o Table Number Sikkim Manipal University Page No. 212 Research Methodology Unit 11 o Title of the Table o Designation of units o B Body o Stub-head, Heading of all rows or blocks of sub items o Body-head: Headings of all columns or main captions and their subcaptions. o Field/body: The cells in rows and columns. o C Notations: o Footnotes, wherever applicable. o Source, wherever applicable. Variables that are classified according to magnitude or size are often arranged in the form of a frequency table. In constructing this table, it is necessary to determine the number of class intervals to be used and the size of the class intervals. The most commonly used graphic forms may be grouped into the following categories: o Line Graphs or Charts o Bar Charts o Segmental presentations. o Scatter plots o Bubble charts o Stock plots o Pictog...
