Session 7.1
Editing and Coding
Introduction
In this session, we look at data editing and coding. This stage of data analysis allows the researcher to transform raw data (the unedited responses of respondents) collected during data
collection into useable data. We will discuss the various methods of coding used by researchers.
We will look at the editing process and we will learn rules for coding and the construction of a codebook. We will learn about various coding devices and software programs used in storing,
processing, accessing, and analyzing data sets.
Learning Objectives
By the end of this session you will be able to: 1. Identify when a response is an error and should be edited
2. Explain how to code qualitative and quantitative data
3. Explain the purpose and construction of the codebook
4. Compare and contrast software used to code and analyse qualitative and quantitative
data
Data Editing
After completing data collection the researcher will need to make sense of the data collected and present it to the decision makers. Fieldwork often produces data that contains errors which
must be removed to ensure the integrity of the data. The process of checking data for
omissions, consistency, and legibility in preparation for coding is called data editing.
Consider the examples provided below and what the researcher/editor should do.
MGMT2063 Research Methods for Business Unit 7_Version 1 5
In the first example, data should not have been collected from the respondent because he did not fall within the target population. The researcher/editor should remove this respondent’s
data from the study. In the second example, the respondent has provided inconsistent
information. The researcher/editor can correct the error by adjusting the answer to the first question to “3” Eastern Caribbean countries travelled to in the last year.
When editing and cleaning data, it is important that the researcher/editor makes “intelligent, experienced, and objective decisions” (Zikmund, Babin, Carr, & Griffin, 2009, p 468) to minimize
interference with the data, avoid bias, make logical adjustments and make ethical decisions. To avoid
having to remove the respondent’s responses, the researcher may need to contact the respondent for
clarification of responses.
Coding Data
Edited data are assigned codes to simplify analysis. Coding refers to the assignment of a numerical score or a classifying symbol to edited data to group data into categories. This
facilitates the entry of data into computer software for analysis. For example, when coding a
response on gender a 1 can be assigned to the response “female” and a 2 for the response “male”:
Female = 0 Male = 1
Note that codes are not always numerical and in qualitative research, numbers are usually not used for codes, words and phrases that represent themes are most common (Zikmund, Babin,
Carr, & Griffin, 2009).
Examples of Need for Editing and Cleaning
Example 1:
A grocery store is studying the shopping habits of young adults aged 18-30. One
respondent indicated that he was 17 years old. What should the researcher or editor do?
Example 2:
A respondent has selected “2” to a question that asked how many Eastern Caribbean
countries were visited in the last year. The same respondent indicates in a later question
that she visited Antigua and Barbuda, Grenada and the British Virgin Islands in the last six months. What should the researcher or editor do?
MGMT2063 Research Methods for Business Unit 7_Version 1 6
Constructing the Codebook
A codebook, also called a coding scheme, contains details on all the codes used in the research.
It can be used to for more accurate and efficient data entry and analysis. The information
contained in the codebook includes:
the variable name
the variable number
the coding scheme
codes
codes for missing data
Using the Codebook
The codebook describes data files which are the files used to conduct analyses. Today data files are computer files that contain the data. In a data editor, such as SPSS (Statistical Package for
Social Scientists), data appear in the form of spreadsheets (figure 7.1) where the data appears as
columns of information representing the different variables. Each column in the data file is equal to one variable from the data file.
Figure 7.1 – SPSS Data Editor
The codebook is useful when using software such as:
SPSS – commonly used for quantitative data coding and analysis
NVivo – commonly used for qualitative data coding and analysis

Session 7.2
The Data Dictionary
Introduction
In the last session you learnt about coding and constructing the codebook. You were also
introduced to software used for compiling data and which will be used to facilitate analysis. In this session we continue the process by learning about database management and the data
dictionary. You will also learn about the procedures for creating a data file and the tasks
involved in data cleaning and data modification.
Learning Objectives
By the end of this session you will be able to: 1. Explain the purpose of using a data dictionary
2. Explain the relationship between data fields, data records, data files and databases
3. Describe the tasks involved in data entry, cleaning and modification
Working with Databases
In preparing data for analysis, the researcher will need to create a database, which is an
electronic representation of the data collected during research. The database allows for the data
to be organized and stored for ease of manipulation and analysis. A database is structured
based on fields, records and files. You will need to distinguish between these terms as you
engage with the resources in this and the upcoming unit.
Field – a field is a single piece of data, such as name, age and occupation, which is each an
answer to a specific question.
Record – a record is a set of data fields that are related to a case or participant, such as all the
responses of one participant in a study.
File – a file is a set of records, such as the responses of all respondents in a study.
MGMT2063 Research Methods for Business Unit 7_Version 1 10
What is a Data Dictionary?
A data dictionary is a collection of descriptions of the data objects or items in a database. It usually serves clarification purposes for the benefit of programmers and other persons involved in the analytic process. Each object must be identified and it must be described in relation to the other objects. Each object must be given a descriptive name. Possible predefined values must be listed and described briefly. The data dictionary is consulted when there is any confusion about any of the data items. The dictionary usually comprises eight columns as shown in Table 7.1. Variable Name
Variable Label
Value Label
Field Type Decimal Field Width
Start End
This column includes the variable name
May be two or three words; represents the variable to be measured;
Labels for the values e.g. the actual sex of a respondent
The value to be given to the code such as alphanumeric values
Number of decimal places
Number of digits in the field
Where the field begins
Where the field ends
sex gender 1 – male 2 – female
numeric 0 1 4 4
Table 7.1 Data dictionary
You will learn more about the data dictionary in Learning Activity 7.2.
Data Entry
Data entry is the process of inputting data gathered into a database for manipulation, storage
and analysis. This is done once coding had been completed.
The software applications mentioned in the previous session, along with other options, can be
used to create databases. The resources provided below show how to enter data in SPSS.

MGMT2063 Research Methods for Business Unit 7_Version 1 11
Data Cleaning
Data cleaning is a very important step to be taken before any data processing can be
undertaken. Similar to editing, it is an important means of quality control. Cleaning allows the
researcher to verify that all values collected are correct or that they conform to certain rules. For example, under gender there can only be one of two values 1 or 2. Some basic checks to be
conducted to verify the data are:
wildcode checking – this is a check which ensures that no impossible codes are entered.
For example entering a 3 under sex.
consistency checking – involves cross checking with other values, fields to ensure the
data is consistent. For example, if the parent admits to having only one child but later on the form the heights of two children are recorded.
Data Modification
Data modification is the alteration of the data. This may be done for the following reasons:
the researcher can combine several indicators to create an index;
to create an index score by adding the data used to code the responses
to rearrange the numerical order of categories.
to create broader categories of variables.
Please complete Learning Activity 7.2 before continuing with the unit. This activity will require you to read further about the data dictionary and data entry and cleaning and participate in a
discussion based on the readings.

Session 7.3
Displaying the Data
Introduction
In the previous sessions of this unit you were introduced to the activities involved in preparing data for analysis. After preparing data for analysis it may be tempting to jump into data
analysis to determine if data support the hypotheses or to answer the research questions.
However, when dealing with statistical data, the researcher should first engage in exploratory data analysis to visualize the data. In this session, you will explore techniques that the
researcher can use to visualize and graphically represent the data to facilitate preliminary
analysis for patterns in data. You will learn about devices such as tables and various types of graphs.
Learning Objectives
After completing the session, you will be able to: 1. Distinguish between different techniques for displaying data 2. Explain appropriate use of different techniques for displaying data 3. Create and interpret visual representations of data
Frequency Tables
A frequency table can be used to present numerical data. The data is easily read and
interpreted when organized in a table form. It is a simple way of arraying numerical data. This
device is useful for showing where no observations occur within the range, which cannot be
captured in a bar chart or pie chart.

Graphs and Charts
Some reasons for drawing charts and graphs are to show frequency, distribution, trends, composition, flows, processes, location and comparisons. The construction of charts and graphs
can be done manually, using traditional methods. However, today this is done more commonly
using software such as Microsoft Excel, SPSS and Minitab.
There are a wide variety of graphs and charts that the researcher can use to analyse data. These
include bar charts, pie charts, line graphs, scatter plots and stem-and-leaf displays. Let’s take a closer look at some of the common techniques.
Bar Charts
Bar charts are used to display number and frequency for discrete categories or groups. These
charts are useful for ungrouped data, but not grouped data (see Figure 7.3).

Histograms
Bar charts cannot be used to present continuous data. However, histograms may be used to
represent continuous random variables (see Figure 7.4). Histograms allow the researcher to easily identify the most popular class in the data and simple patterns in data.

If you are having trouble understanding any of the charts and graphs that we just discussed, remember that there is a wide variety of tutorials available online.
Presenting Data in Reports
It is important that you understand appropriate use of the display techniques to
facilitate preliminary data analysis and for use in reports to be read by others. Although
we are focusing, in this session, on displaying data for analysis, you should note that
the formats used above can also be used for displaying data in reports during the
presentation stage of research as a means of summarizing results. When used for this
purpose, there are design factors that the researcher will need to consider to ensure ease
of interpretation by persons who are not as intimate with the research and the data. You
may find the resource provided below to be useful.

Unit 7 Summary
This unit focused on data preparation and presentation. This involves editing and coding data, centering and cleaning data and displaying data for analysis. You learnt that quality control is very important throughout preparation of data for analysis, which is why data should be edited and cleaned at the respective stages in the process. You also learnt that data may be more difficult to analyse and interpret unless it is appropriately displayed in a visual form. Having completed preparation for data analysis, you are now ready to analyse the data. You will cover this topic in the next and final session of this course.
