Data analysis is the process of bringing order, structure and meaning to the mass of collected data. It is a messy, ambiguous, time-consuming, creative, and fascinating process. It does not proceed in a linear fashion; it is not neat. Qualitative data analysis is a search for general statements about relationships among categories of data

Data analysis helps to make sense of our data otherwise they will remain a
pile of unwieldy information; perhaps a pile of figures.
To answer the research

• Numerical values obtained from the
sample that gives meaning to the data
collected.
• Use percentage, mean, median, mode,
range and Standard Deviation.
• Drawing conclusions based only on sample
data beyond the immediate data.
• E.g. Use t-test (difference between the
means of two independent groups),
ANOVA (to test the significance of
differences between means of two or
more groups).
10. Descriptive
10
You own a restaurant and want to know how your business is being
perceived by people. So, you give one of your staff, Amy, the
responsibility of carrying out a small survey of your customers to
see how they feel. Amy goes head on to collect information from
every client who visits your restaurant. At the end of the week, Amy
comes to you with a giant grin on her face and hands to you a long
list of numbers that contain how many points each client has given
your business. You stare down at this soup of numbers and scratch
your head as you have no idea what to make of it! You’re probably
considering firing Amy at the moment, right?
An example of real case
11. 11
Well, Amy’s efforts weren’t exactly in vain, but what she
should have done instead of just handing you a bunch of
numbers was to represent these numbers in a more
meaningful way so that you could make a proper inference
from them. This is where statistical analysis comes into
play.
An example of real case
12. Descriptive
12
Amy got hold of about 100 customer feedbacks. Say your
customers filled out a survey form where they scored your
restaurant on a scale of 1 to 10. She could have organized
these scores into a chart or graph to let you pictorially deduce
how many of your customers think your food rocks. Assuming
75 of them gave you more than 5 points, while 25 of them gave
you less than 5 points. It would serve you better if Amy had
created a Pie chart that clearly indicated what percentage of
your clients/customers love you. In this case, you could easily
see that 75% percent of your customers like you, so you’re right
on track!
An example of real case
14. Descriptive
14
Amy could also have calculated an average of all the scores to give
you an idea of the general client sentiment. So, if most of the clients
scored you between 6 and 7, your average would come to around
6.5, showing that it’s not all the bad, but you could do better. There
are many other ways to visualize data or draw an inference from a
limited set of data. These include other measures of central
tendency like mean, median and mode as well as measures of
dispersion, like variance and standard deviation. These values can
give you an idea of how varied the opinions of your customers are.
Altogether all these measures and visualizations could give you a
pretty good idea about how your business is doing.

“…to discover and describe issues in the
field or structures and processes in
routines and practices. Often, qualitative
data analysis combines approaches of a
rough analysis of the material (overviews,
condensation, summaries) with approaches
of a detailed analysis (elaboration of
categories, hermeneutic interpretations or
identified structures). The final aim is often
to arrive at generalizable statements by
comparing various materials or various
texts or several cases.”

The analysis of qualitative data can have several aims.:=A
Subjective experiences of a specific individual or group. Can compare and contrast on the case/s (individual or
group) and its special features and the links between them.
Explaining such differences (e.g. circumstances which make it more likely students to learn drawing with
a specific situation more successful than other students).
Based on the phenomenon under study from the analysis of empirical material (e.g. a theory of art making), a
theory is developed.

QDA is the range of processes and procedures whereby the data that have been collected is
explained based on the understanding or interpretation of the people and situations we are
investigating. QDA is usually based on an interpretative philosophy. The idea is to examine the
meaningful and symbolic content of qualitative data.

Five Type sof Qualitative Analysis
Descriptive – What’s the data?
Interpretative – What was meant by the data?
Refers to a cluster of analytic methods for deciphering texts
or visual data that have a storied kind.
Involves real text not invented, created and artificial text.
Five distinct phases: Familiarization, Identifying a thematic
framework, Coding, Charting, and Mapping; and Interpretation.
Analysis and development of theories happen when you
have collected the information.
29. What’s Content Analysis
(CA)
Content analysis is the study of documents
and artifacts, which might be texts of various
formats, paintings, pictures, audio or video.
Social scientists use content analysis to
examine patterns in communication in a
replicable and systematic manner.

Can be both quantitative (focused on
counting and measuring) and qualitative
(focused on interpreting and
understanding).
In both types, you categorize or “code”
words, themes, and concepts within the
texts and then analyze the results.
Prof. Dr. Nasir | UPSI 30
31. How to conduct content analysis
Prof. Dr. Nasir | UPSI 31
5 STEPS:
Select the content
you will analyze
Choose the texts that you will analyze. If there are
only a small amount of texts that meet your
criteria, you might analyze all of them. If there is a
large volume of texts, you can select a sample.
1. Develop a set of
rules for coding
Organize the units of meaning into the previously
defined categories. it’s important to clearly define
the rules for what will and won’t be included to
ensure that all texts are coded consistently.
3. Analyze results and
draw conclusions
Find patterns and draw
conclusions in response to
your research question and
make inferences.
5.
Define the units
and categories of analysis
The unit(s) of meaning that will be coded. The set of
categories that you will use for coding. Categories
can be objective characteristics (e.g. female, aged
40-50, lawyer, mother) or more conceptual (e.g.
trustworthy, corrupt, conservative, family oriented).2.
Code the text
according to the rules
Go through each text and record all relevant data in the
appropriate categories. This can be done manually or aided
with computer programs, such as QSR NVivo, Atlas.ti and
Diction, which can help speed up the process of counting
and categorizing words and phrases.4.
32. Coding Qualitative Data:
How to Code Qualitative Research
• What is coding in qualitative research?
1. Coding is the process of labeling and organizing your qualitative data to
identify different themes and the relationships between them.
2. When coding, you assign labels to words or phrases that represent important
(and recurring) themes in each response.
3. These labels can be words, phrases, or numbers; we recommend using words
or short phrases, since they’re easier to remember, skim, and organize.
4. Thematic analysis is done to find common themes and concepts. Thematic
analysis extracts themes from text by analyzing the word and sentence
structure.
30
33. Types of Coding
33
Two Types of Coding
Deductive Coding
Deductive coding is also called concept-driven
coding. Start with a predefined set of codes.
These codes might come from previous
research, or you might already know what
themes you’re interested in analyzing.
Inductive Coding
Also called open coding, starts from scratch
and creates codes based on the qualitative
data itself. You don’t have a set codebook; all
codes arise directly from the responses.
34. Deductive Coding
34
Deductive coding is a top down approach where you
start by developing a codebook with your initial set
of codes (pre-set coding schemes)
This set could be based on your research questions
or an existing research framework or theory.
Researcher’s setup the codes based on emerging
themes and define them according to the source
(e.g. literature review, support, etc.).
Once the coding scheme is established, the
researcher applies the codes to the text.
What is deductive Coding?
35. Inductive Coding
35
Involves the conversion of raw, qualitative
data into more useful quantitative data.
Unlike deductive analysis, inductive
research does not involve the testing of
pre-conceived hypotheses, instead
allowing the theory to emerge from the
content of the raw data.
What is Inductive Coding?
36. 36
What’s Narrative Inquiry
Relatively new qualitative methodology.
The study of experience understood narratively.
Narrative inquirers think narratively about experience
throughout inquiry.
Uses a recursive, reflexive process of moving from field (with
starting points in telling or living of stories) to field texts
(data) to interim and final research texts.
Commonplaces of temporality, sociality, and place create a
conceptual framework within which different kinds of field
texts and different analyses can be used.
Highlights ethical matters as well as shapes new theoretical
understandings of people’s experiences.

What’s Narrative Analysis
(NA)
The social constructionist perspective is that all
‘narratives sit at the intersection of history,
biography, and society’ (Liamputtong and Ezzy
2005: 132); they are dependent on the context
of the teller and the listener; and are not
intended to represent ‘truth’.

38. How to analyse?
Texts are analysed within their social, cultural, and historical
context.
Deconstructed to search for themes and subthemes, in order
to build up a theory grounded in the data.
Different researchers have their own style of narrative
analysis.
The Foucauldian examines multiple voices and to draw out
which voices were silenced and which were powerful. ‘The
interpretation we call truth is the one that is attached to
power’ (Byrne-Armstrong 2001: 113).

40. What’s Discourse Analysis
(DA)
A research method for studying written or spoken language
in relation to its social context. It aims to understand how
language is used in real life situations.
Discourse analysis is a common qualitative research
method in many humanities and social science disciplines,
including linguistics, sociology, anthropology, psychology
and cultural studies.
40
Publisher: Routledge
Year: 1999
41. 41
You make interpretations based on both the details of the material itself and on contextual knowledge.
Step 1: Define the research question and
select the content of analysis
Begin with a clearly defined research question.
Then, select a range of material that is appropriate
to answer it.
Step 3: Analyze the content for themes
and patterns
Closely examine various elements of the material –
such as words, sentences, paragraphs, and overall
structure – and relating them to attributes, themes,
and patterns relevant to your research question.
Step 2: Gather information and theory on the
context
Establish the social and historical context in which the
material was produced and intended to be received.
Understanding the real-life context of the discourse,
you can also conduct a literature review on the topic
and construct a theoretical framework to guide your
analysis.
Step 4: Review your results and draw
conclusions
Once you have assigned particular attributes to
elements of the material, reflect on your results to
examine the function and meaning of the language
used. Here, you will consider your analysis in relation
to the broader context that you established earlier to
draw conclusions that answer your research question.
43. What’s Grounded Theory
Analysis (GTA)
A type of scientific research concerned with the
emerging concepts of social phenomena.
It refers to situations where data collection is
conducted in an unstructured way (Joubish,
Khurram, Ahmed, Fatima, & Haider, 2011)

What’s Axial Coding?
Axial coding is a qualitative research technique that involves relating data together in order to
reveal codes, categories, and subcategories ground within participants’ voices within one’s collected
data. In other words, axial coding is one way to construct linkages between data.
Axial coding is the breaking
down of core themes
during qualitative data
analysis. Axial coding in
grounded theory is the
process of relating codes
(categories and concepts) to
each other, via a
combination of inductive and
deductive thinking.

• Describing relevant
excerpt selected
• Creating a code that

mind)
51. Selective Coding
51
Selective coding is the process of choosing one category to be the core category, and relating all other categories to
that category. The essential idea is to develop a single storyline around which all everything else is draped. There is a
belief that such a core concept always exists.

55. A visual analysis is used to
communicate how the aesthetic or
formal qualities of an image relate
to seemingly relevant ideas,
histories, narratives, politics,
cultures, affects, and/or
experiences. In other words, visual
analyses are used to show how
particular visuals create specific
effects and/or affects.
55
56. Visual analyses often involve a
combination of writing styles. This can
include observant, technical, emotive,
critical, reflective, and/or speculative
modes of writing about images. Visual
analyses can vary in length from a few
sentences, to a paragraph, to an entire
essay
56
57. • To create a coherent and clear
• interpretation of an image, it is
recommended that you do
three things:
• describe, analyse, and
interpret.
57
58. • descriptive, and visual language, tell the
reader what the image looks like.
• The subject matter and how it
• has been composed.
• Detail the formal and structural qualities of
the image (such as the tonal, linear, and
textural characteristics of the image). You
may also wish to describe how the image
has been made and exhibited.
• Consider the affective and experiential
qualities of the work;
• Consider step one in relation to the
image’s context and seemingly
associated concepts.
• Relate to specific theoretical framework.
• Provide the reader with a concluding
remark (take the image as their focus)
that clearly articulates the overall
impact – or, perhaps, ‘meaning’ – of
your selected image. Sometimes you
may arrive at multiple, even
conflicting, interpretations of a work.
58
How should you structure a
visual analysis of a an art
work?
