Dissertation Structure Title Abstract Table of Contents Table of Figures Table of Tables Introduction (starts at page 1) Literature Review (can be separate chapters) Your Design Your Findings Your Evaluation Conclusion and Future Work
Introduction Aim is to introduce the reader to
The project Its background Justification that the project is viable Your project aims You project objectives Your research approach Any scope or limitations Overview of the rest of the dissertation
10-15 pages (approx. 10% of the dissertation)
Background/Literature Review Aim is to provide the reader with your insight
into the body of literature Introduce key terms, definitions, ideas, thought
leaders Provide critical analysis of existing approaches,
techniques etc. Identify key ideas, themes, issues or directions
that informed your approach Set the scene for why you will be doing things the
way you will do things for your project 20-25 pages (approx. 20- 25% of the
dissertation) Can be split into multiple chapters
Your Project = 60% of the dissertation Generally you need a chapter for each of the
following: Design/Formulation of proposed
experimentation/implementation Should be clear how the literature reviewed has
influenced design Should be clear why research approach is suitable
Experimentation/Implementation Should align with proposed approach Should discuss clearly any deviation/adjustments
needed with justification Analysis of your findings
Should honestly discuss the outcome of your experimentation
Should draw conclusions about your work
Conclusion and Future work Approx. 10% of dissertation Should mirror your introduction
Should address how well you have addressed the aim and objectives
Should assess where and how well your work aligns with existing research
Should discuss scope and limitations Should provide detail about potential future work
To build on your experimentation Alternates to your experimentation Other avenues in which your work can be applied Etc.

Interview
Issues to be Discussed – Interview Design Justification for use as a tool
Relate back to qualitative research
Relate to your project State clearly
Interview Aims Interview Objectives Relationship to project Choice of Interviewees
(audience, sample) Profile Skills Justification of suitability
Make transparent any constraints
Question design Each question should
address certain objectives
Outline clearly this relationship
Think clearly about the question wording Is it suitable for your
interviewees? Is it suitable to elicit
the knowledge you need?
Issues to be Discussed – Interview Execution Who
Profile, how many etc. When
Dates, times, duration Where
Location, surroundings, anything that influenced How
How long, one to one, recorded, over Skype etc. What
Exactly what happened, any issues – hesitancy, lack of understanding of questions, additional questions, suggestions etc.
Why For all the above why were things done in this way, why did
certain things happen etc.
Issues to be Discussed – Interview Findings Transcribe your interviews
You need to include the transcription
Not within the main dissertation but as an appendix
Can be included on a CD Analyse your data
Summarise, organise and extract meaning from interview transcripts
Coding Identify Major Themes Align to aims and objectives
Of interview Of project To literature
Present summary statistics
Draw Conclusions Determine key issues to be
addressed Identify recommendations
Be aware of bias Make it transparent
Validate findings and conclusions Expose to some interviewees Look for independent
verification – literature, other research tools used
Review and revise conclusions to ensure that they are reliable and valid
Bias What is bias?
All views of reality are filtered. Bias only exists in relation to some reference point.
Types of bias: Motivational bias
Interviewee makes accommodations to please the interviewer or some other audience
Observational bias Limitations on our ability to accurately observe the world
Cognitive bias Mistakes in use of statistics, estimation, memory, etc.
Notational bias Terms used to describe a problem may affect our
understanding of it
Examples Social pressure
response to verbal and non-verbal cues from interviewer
Group think response to reactions of
other experts Impression management
response to imagined reactions of managers, clients,…
Wishful thinking response to hopes or
possible gains Appropriation
selective interpretation to support current beliefs
Misrepresentation expert cannot accurately fit
a response into the requested response mode
Anchoring contradictory data ignored
once initial solution is available
Inconsistency assumptions made earlier
are forgotten Availability
some data are easier to recall than others
Underestimation of uncertainty tendency to underestimate
by a factor of 2 or 3
Terminology Theme
a topic that organizes a group of repeating ideas.
usually developed during focused coding, but may emerge during literature supported by interview findings
E.g. from analysis of interviewee responses, it emerged that that employees are reluctant to use the Wiki as they view the contents as out of date and stagnant.
Making conclusions/recommendation a determination of what is
working well and what needs to be improved based on repeating ideas and themes.
Themes and repeating ideas should guide you in recommending or making improvements.
E.g. in response to the view of the Wiki as stagnant and out of date, the project will introduce social media tools alongside the Wiki to encourage more informal knowledge sharing
Issues to be Discussed – Interview Findings Report repeating
ideas/issues Repeated by a number of
interviewees Report meaningful
responses Those that most exemplify
issues or support recommendations
Quantify these How many people said this? How many disagreed? Why are they best situated
to comment? Include quotes
Present Graphically Organise themes and
conclusions into tables or trees
Demonstrate relationships
Interviews Unstructured interview
Free flowing, used in early stages of elicitation/research, can produce basics of knowledge domain, basically broad chat
Semi-structured interview Main technique Pre-defined questions sent to expert prior to
interview, supplementary questions asked at interview. Can be used as part of validation.
Structured interview Pre-defined set of questions, can simply be filling
in a questionnaire at the interview.

Quantify these How many people said this? How many disagreed? Why are they best situated to
comment? Include quotes
Present Graphically Present outcomes of
key questions or question groupings as charts or diagrams
Organise themes and conclusions into tables or trees
Demonstrate relationships
Questionnaires Keep questions short and simple Avoid questions with “not” Avoid questions with bias Avoid sensitive questions (ask indirectly) Do not ask compound questions, just ask
one question at a time e.g. "Do you know what services are available to
you and how to find out?"
Questionnaires Likert scales
Poor, Weak, O.K., Good, Excellent Very Low, Low, O.K., High, Very High 1, 2, 3, 4, 5
Descriptive and Inferential Statistics
Measure of Central Tendency Central position of a frequency distribution for
a group of data Possible measures: mode, median, and mean. Mean: The arithmetic average of a group of
scores; the sum of the scores divided by the number of scores.
Median The middle score of a sequence of all the scores in a distribution arranged from lowest to highest.
Mode The value with the greatest frequency on the distribution
Examples
Measures of spread Ways of summarizing a group of data by describing how
spread out the results/findings Normal Curve: A specific, mathematically defined, bell-shaped
frequency distribution that is symmetrical and unimodal; Normal Distribution: A frequency distribution following a
normal curve. Skewness: The extent to which the majority of cases in a
frequency distribution fall to one side of the middle. Inter-quartile range: The range of the middle 50 per cent of all
scores in a distribution when arranged from lowest to highest. Standard Deviation: A measure of the degree to which scores
in a distribution vary from the mean. Variance Another measure of the degree to which scores in a
distribution vary from the mean (equal to the standard deviation squared).
Way to Present Data Interval or Ratio Variables
Mean and Standard Deviation (if approximately normally distributed)
Median and Interquartile Range (if skewed and thus not normally distributed)
Histograms Boxplots Stem-and-Leaf Displays
Interval variable: A variable with actual values rather than categories e.g. salary
Ration variable: As with interval variable but with added characteristic that there is a true zero value e.g. age
Way to Present Data Ordinal or Nominal
Mode and/or simple frequencies Barcharts Piecharts Tables
Nominal variable: A variable that consists of two or more categories. E.g. male or female Ordinal variable: A variable that consists of
categories that can be rank ordered in relation to being 'more' or 'less' of the concept in question. E.g. age ranges 16-20 etc.
