3. We can effectively recall
20% of what we hear;
30% of what we see;
50% of what we hear and see;
70% of what we do.
So it is clear that we must allow the audience to see, and hear and interact with the presenter and the presentation material.

4. A presentation must tell them what they need to know;
show them as much as is necessary
create opportunities for interaction

5. Some Presentations are
Too long
Too short
So Keep It Short and Simple

6. Short and Simple presentation
About 20 minutes (including the introduction and the conclusion) you have time for only two major points.
In 30 minutes you might make three major points.
In 40–45 minutes you might be able to cover four major points, but three points and a longer time for questions would be a better alternative.

7. Presentation Time

8. Starting the presentation
List of things planned to say

9. The ‘keyword’ in the central box should be a one or two word abbreviation of your primary objective.
Use just one or two words on each ‘limb’, even a whole phrase if necessary – but never a complete sentence.
Use the full range of colours you have available.
If different parts of the spidergram seem to link up, indicate this fact with a linking arrow rather than duplicating a whole set of ‘limbs’.

10. Creating a structure
Make a structure to presentation. Make understanding of the points you are making as you go along.
Do not try to say
‘which I will explain later on’ and ‘I’d like to add some comments to something I said earlier about…’
Effective way to create a structure for you presentation is to take the main points you plotted on your spidergram

11. Factors considered ….. Have I introduced the subject clearly
Does the presentation follow a clear sequence from start to
finish?
For ex: ‘B will depend on A, which I described earlier…’ is far better than ‘Of course, B will depend on A, and I’ll tell you more about A in just a minute…’
Have you broken the information down into ‘digestible’
chunks
Do your closing remarks genuinely wrap the presentation up and show how everything fits together?

12. Selecting and using visual aids
Visual Learning- Films, Movies, Books- 90%
Hearing %
Remembering-
Verbal 70% l( 3hrs later)
10% After Three Days
Only Visual 75% ( After 3hrs)
20% (after Three Days)
Visual and Verbal
85% ( after 3hrs)
66% ( After Three days)
A truly powerful and memorable presentation you will need to include some form of visual aid.

13. Select the Visual Aids
Think carefully which form of visual aid is suitable
Chalkboard
Whiteboard and pen
Flipcharts
Overhead projector (OHP)
Computer-based displays

14. Vocal Interest = 38 percent Body Language = 55 percent
Points that make a point
Three ways to express
Vocal Interest = 38 percent
Body Language = 55 percent
Verbal content = 7percent

15. Chart

16. Eye catching

17. Use of Chart and Graph Keep It Short and Simple :
If the audience does not get the message in five to ten seconds, they’ll be watching the screen
Careful use of colours.
Use four lines per graph at most, and use a different colour each line.
Line graphs are best.
Avoid vertical labels in a line graph.

18. Example

20. To minimise the differences in a chart or graph make the X axis (the base line) as long as possible
To maximise the differences in a chart or graph make the vertical Y axis as long as possible.

21. Example

22. In any kind of bar chart, limit each display to six or seven bars (or groups of bars) at the most.
Use a vertical bar chart (with bars running from top to bottom) to compare related data at several points in time.

23. Example

24. It is sometimes quite difficult to compare the information in different bars in a ‘stacked’ bar chart.
So only use ‘stacked’ columns if the precise make-up of each column is relatively unimportant, otherwise groups of adjacent bars are more effective.

26. When using a histogram always arrange the bars in ascending or descending order of magnitude, not in alphabetical order.
A pie chart is often the best way of illustrating the relative values

27. Example Always put the labels for a pie chart outside the chart.
Keep pie charts down to a maximum of six or seven wedges.

28. Use a ‘floating wedge’ when you want to focus attention on that particular section of the pie

29. Using colours Color for text-No rainbow effect.
Two Or three colors in single display is fine
More than three- Excessive ( 5 or more Mind Boggling)
Use same color code
For: Black for text
Red for keyword
Blue for secondary text
Always remember that red and green are the two colours most frequently involved in cases of colour blindness
It is a good idea to avoid these two colours when you want to emphasise a difference or a comparison.

30. Color selection RED Color: emphasise.
A bright, warm yellow - for attracting attention [royal blue, dark Green background] [sunshine, summer, warmth].
Dark blue - desire for relaxation [explain unimportant items]
Light blue, like yellow - positive connotations linked to clear skies, sunny days
