This document provides tips and guidelines for creating better presentations. It discusses understanding communication theory and developing skills with computers, vocabulary and photography. PowerPoint is presented as a tool to support presentations, not replace the presenter. Non-verbal communication and body language are important. The document stresses the importance of planning, preparation and practice. Visual aids like images, graphs and tables should enhance the content without being cluttered. Effective delivery requires practicing techniques like maintaining eye contact and avoiding distracting mannerisms.

- do not clutter
- colour contrast
- explanatory key*
* the gist or statistical conclusion
should be summarised in a line or two !

28. Scatter diagram showing the linear relationship
between peak pressure of the great toe in the left foot
and weight in 90 subjects.
Formula :
Peak pressure =151.5 + 1.41 x weight
The regression coefficient or slope of the line,
estimated by 1.41 (95% CI 0.67 to 2.15) kPa per kg of weight,
implies that, on average, as a subject’s weight increases by 1 kg,
the peak pressure under the great toe in the left foot increases by about 1.4 kPa;
the slope is significantly different from 0 (p < 0.001)
so that the subject’s weight is an important predictor
of the peak pressure under the great toe.

…there is a linear
rise in pressure
with increased
chances of
ulceration

7 lines/ page
 Parallel construction of lists
 SPELLING, SPELLNIG, SPELLING
Better still: rule of 5

35. Mixing Important / Unimportant Words
Ex: Computers in hospitals
 The isoefficiency and the scalability
metrics of a parallel algorithm are
crucial
 The typical parallel computers of the
future will have thousands of CPUs
and terabytes of RAM

36. Hospital Computerisation
 Crucial dynamics
- isoefficiency
- scalability of function
 Future systems
- thousands of CPUs
- terabytes of RAM

37. Slide rules
 Appropriate
 Accurate
 Legible

 Interesting
 Memorable

38. Powerpoint evils
Backgrounds, Text, and in
Particular Animation Should
