3. Preparing visual aids
How will you present the information?

4. Readers can get the same data from various visually- oriented representations, but they will experience different rhetorical effects.
Table
Figure

5. Table
Use it when your readers are likely to want very precise numbers, and you don’t want to impose on your data a visual image implying the point you want them to support.
It lets your readers compare the numbers systematically and come to their own conclusion.

6. Figure
It is useful when your readers are less interested in precise details than in a general point, and you want to reinforce your point with a strong image.
Line graph
Bar chart
Stacked bar chart
Horizontal bar chart
Centrally divided horizontal bar chart
Pie chart
Have you ever used any of them in your presentations?

7. Line graph
It gives less exact information but offers a more striking image of a story. It helps readers see trends easily.

8. Bar chart It visually communicate the gist of its point quickly.
It also helps readers to make individual comparisons.

9. Stacked bar chart
It divides the bar into its relative proportions of 100 percent of some other variable.
It could be difficult to process because they force readers to make comparisons and gauge proportions by eye alone.

10. Horizontal bar chart
The only advantage of a horizontal bar chart over a vertical one is typographical: it lets you get the whole name of an item next to a bar

11. Centrally divided horizontal bar chart
It puts two dependent variables on either side of a center line and then displays a number of independent variables.
The same data can be presented in a side-by-side vertical bar chart.
But it is typographically more difficult to do.

12. Pie chart Favorites of newspapers and annual business reports.
It allows readers to see crude proportions among a few elements that constitute 100 percent of a whole.
But they are hard to read when they have more than 4 or 5 segments.
Foe example: Russian and Portuguese—which one has more speakers?
Difficult to judge size.

13. DON’T!!

14. DON’T!!
