3. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Editing, : Editing is the process of checking and
adjusting the data for omissions, legibility, and
consistency. Editing may be differentiated from
coding, which is the assignment of numerical scales
or classifying symbols to previously edited data.
There are various variables, which need to be edited,
they include:
3

4. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Editing, : Types of editing are:
1. Validation Edits: The researcher checks its validity.,
2. Logical Edits: The researcher satisfies, that two data
are not contradictory.,
3. Consistency Edits: The researcher satisfies, that
‘Consistent or correct arithmetic relationship is
found between data items.,
4

5. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Editing, : (Contd…)
4. Range Edits: The researcher satisfies, that data
values fall in the acceptable range.,
5. Variance Edits: The researcher satisfies, that that
every data has a uniform variances., (there exists no
high variance between 2 variables).,
6. Micro-Editing and Macro-Editing: The researcher
distinguish in order to calculate the range of edits, in
his research. 5

6. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Editing, : Hence editing is one of the most important
activity to eradicate, minimize, detecting and
correcting errors in data. (Error Free Questionnaire
and so on).
Editing helps the researcher to collect only those
relevant data for his research and omit those which
are irrelevant for his research.
Editing makes to deduct errors, fill the missing data
and make the data complete for next step in research.

7. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Coding, : Coding is translating answers into numerical
values or assigning numbers to the various categories
of a variable to be used in data analysis.
Coding is done by using a ‘Code book’, ‘Code Sheet’,
and a ‘Computer Card’.
Coding is done on the basis of the instructions given in
the codebook. The code book gives a numerical code
for each variable/ specification or description.
7

8. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Coding, : Coding is usually done after examining the
each scale, and allocating the appropriate number
stating the proper range between the different scales.
In brief it can be said that ‘Coding’ is the conversion
of verbal (Qualitative) values to numerical
(Quantitative) values, therefore the study can be
more specific with relevant values.

9. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Time of Coding, :
1.Before examining the data collected., (Applicable
in Deductive Hypothesis – Those research is based
on Theory is the Deductive Hypothesis)
2.After examining the data collected. (Applicable in
Inductive Hypothesis – Those study which are based
on ased on Observation)

22. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Tabulation, After editing, which ensures that the
information on the schedule is accurate and
categorized in a suitable form, the data are put
together in some kinds of tables and may also
undergo some other forms of statistical analysis.
Table can be prepared manually and/or by
computers. For a small study of 100 to 200 persons,
there may be little point in tabulating by computer
since this necessitates putting the data on punched
cards. 22

23. 14MBA23 – RM – M5
Preparing the Data for Analysis:
Tabulation, Tabulation is the systematic presentation
of numerical data in rows and columns, classified
each with its characteristics, which displays a
accurate, clear and easy to understand the data
represented in the form of table.
