Proposal:
Preliminary Results and Discussion
Dos and Don’ts
Do
Don’t
 Include initial results if you have
 Insert figures without
them
 You can also conduct and report
on informal pilot studies
 Anticipate results
 Maybe make graphs to show
potential relationships
 Potentially include results from a
related project
 And discuss how your results may
be the same or differ
 Write text before citing figure
 Write captions for each figure
explanatory text or
captions
 Leave this section blank
because you have not yet
generated formal results
Integrate Figures With Text
Making effective plots:
1. Don’t use default Excel plots!
2. Figure should highlight the key relationships in the
data.
3. Should be clear - no extraneous legends, lines, only use
annotations when they add real explanatory value.
4. Don’t use bells and whistles like 3-D when they don’t
improve clarity.
5. Make sure fonts are large enough to be read both in
print and on screen.

What’s wrong with this graph?
Lines too thin
Symbols pretty small
Axis labels too small, not uniform
size
Poor choice of axis scales
Zero on Y-axis is off graph origin
Y = 0.97X + 0.10, R2 = 0.745, n = 145
Improvements
Lines thicker
Symbols bigger
Axis bigger font, bold, uniform
Axis scales match data range,
changed to log scales
Added regression line and equation
The much-abused Pie Graph
(try to avoid them)
(consider stacked bar graphs)
Fonts too small
Bad color choices: slices not distinguished by
shading
Too many data groups (categories)
Fixes
Combined categories
Better shading / color scheme
Enlarged fonts
Unboxed the legend (remove excess ink)
What is wrong with this?
What is effective from these variations?
Bar plots vs. box plots
- Appropriate for counts without variation
- Emphasis on comparing means
- Error bars show some variation (if included)
- Shows rough distribution of data, including
outliers
- Conveys much more information in same
amount of space (customizable, but usually
median, quartiles, 95% range, outliers)
For presentations, use color, make thick lines, larger fonts
Use diagrams and cartoons to illustrate concepts and describe methods
