Need for Research Reporting
Complicated motion in tiny parts
Random and structureless
Naturalistic setting
Experimental Work vs Observational Work
Can lack luxury of laboratory conditions
Cannot filter out unwanted variables and outside effects
Work alongside randomness and uncontrollable factors
Good methodology = Good tool
Random walk
Heads
15 Heads & 14 Tails
What is underlying this “random” behaviour?
Tails
A monthly index of the price of tea?
The relief of a mountain range?
The audience ratings for a movie?
Blood pressure?
Heads and tails?
When the methodology is revealed, things don’t seem so “random”

The
Dissertation
Process
Purpose
“substantial piece of academic work”
taught research methods module
suitable review and publication style
parity with academic peer review journal - although rather longer
clear, concise and should be approximately (set) length
(excluding references, appendices and tables).
excessive length discouraged - does not earn extra marks.
Purpose
investigation into occupational health, safety, or environment
specific question
potential problem
scientific manner
formal hypothesis testing
practical projects involving collection of data and subsequent analysis
“demonstrate student’s ability to define a problem, review relevant published
literature, to plan and carry out the collection, analysis and interpretation of
the data, to draw conclusions and to make suitable recommendations”.
Protocols
sound out course tutor / academic staff with ideas
think about project soon
consult lecturers, tutors, employers
supervisor assignment
reading around the subject area
familiarity with key publications
recent developments
type of study and design
feasibility need to be thought out as far as possible

Planning
the
Dissertation
Considerations
“What things do I want to say ?”
“Does it answer the research question ?”
“Is the report worth writing ?”
“Does it match with my protocol ?”
“Have I done this work before ?”
“What is the correct format for the message ?”
“Who is my audience ?”
“Would it be good enough for a journal submission ?”
Structure

Title
Twenty research projects into
“Managers’ attitudes to health and safety and workers’ accident rates”
Soul-destroying
Use a little journalism or hyperbole

is not as effective as
“A new treatment for colds”
Do not be too comical or glib
Title Guidelines
Simpler the better

Brevity is best
Avoid excessive adjectives and noun-strings
Don’t be too sensationalist - think of audience / examiner / journal

a study into the effectiveness of Fluoxetine Hydrochloride
Uses Why you did it, What you did, What you found, and What you concluded
STUDY DETAILS:
•Comparison of Fluoxetine and another established anti-depressant (MAOI).
•Subjects were nurses in a Manchester NHS district hospital.
•All subjects were suffering clinical depression.
•48 received Fluoxetine and 52 received the MAOI once a day for 6 months.
•At start, 3 months, and 6 months on, mental health scores were recorded
•No difference was found between the 2 groups at the start and 3 months on.
•At 6 months, scores were significantly different (P=<.05).
•Fluoxetine subjects had scores ranging from 2 - 40 (mean GHQ score of 22).
•MAOI subjects had scores ranging from 17 - 82 (mean GHQ score of 47).
Fluoxetine is a novel compound for the treatment of reactive depression, but so
far only anecdotal reports have indicated that it is effective. We attempted a
controlled trial in NHS nurses
A randomized double blind study of consecutively encountered clinically
depressed employees from a large NHS district hospital in Manchester was
undertaken. Fluoxetine (20 mg / day) was compared with MAOI. Participants were
assessed at 0, 3, and 6 months by a standardized psychometric test, and their
DID
socially adjusted mental health scores recorded
One hundred volunteers were recruited, of whom 48 received Fluoxetine and 52
traditional MAOI. There was no difference in the in the adjusted mental health
scores at 0 and 3 months, but at 6 months those in the Fluoxetine group had a
range of scores of 2-40 (mean 22) compared with 17-82 (mean 47) in the other
group, showing a difference in median score of 25 (95% confidence interval)
FOUND
For the relief of depression in health service workers at least, Fluoxetine appears
to be significantly more effective than MAOI, but only after being taken for more
than 3 months.

Introduction & Literature Review
Bring the reader upto speed
Why this research?
Identify knowledge gap
Review the relevant literature
(not Darwin)
Cite references to justify research
Brevity
State clearly what research question is
Provide a reference for every fact or claim made
Clarity is essential
(if methodology not clear, then neither will be the Introduction)
Methodology
Describe the work accurately enough to allow replication
Little salvation for flawed / inappropriate methodology
Little remedy at report writing stage
Indicates trustworthiness of research
Gaps & Vagueness
Would a qualified reader be able to replicate the work from reading report?
Being honest?
Did it happen as claimed?
Methodology guidelines
How n was chosen
How subjects were chosen (sample frame) and contacted
How subject selection was randomised (if the case)
Reason for inclusion / exclusion of subjects (list criteria)
Ethical features or special considerations
List materials / equipment used (not pencils!)
Give exact measures e.g. exposure sizes, metrics, tests, drug doses etc.
Be specific and detailed when it is technical
Use a diagram if the study design is complex
Results
Summaries of data
(not raw data)
Mixture of text, tables, graphs, and diagrams
Results of statistical analyses
Descriptive analyses:
how many respondents
how many men / women
demographics
Inferential analyses:
significance tests
association tests
regressions
modelling
include Means, Standard Deviations, P-values etc
Results guidelines
Start with descriptive statistics
e.g. response rate, how many of each sex, age distribution
data to describe who the sample are - humanise them
Then present inferential statistics
e.g. significance tests, correlations
data which answers specific questions / objectives
Tables and illustrations must stand alone - titles essential
Graphs need both axes labelling
Prepare and format tables to an identical style and stick to it
Don’t over present tables with excessive colours or fonts
Present a final sub section - “summary of results”
bullet point the main findings
Tables & Figures
Present a separate table listing all the tables in the report
(each table consecutively numbered & show page number)
Present a separate table listing all the figures in the report
(each figure consecutively numbered & show page number)
Keep format identical to the larger Table of Contents
Tables
numbered consecutively e.g. Table 4
have the same margins as the main text
sufficient title
whole page tables should be page numbered
each table should be individually discussed in the report
