Males behaving in a territorial manner to other males were
observed at least once on
60% of the weed patches in the study area during the main period of observation, and
slightly under half of the patches were more or less continuously occupied by
territorial males (Table 1).
The rate of oviposition events was positively correlated with the mean
flow rate
recorded for a weed patch (Figure 2).
Data
- Numerical data are normally presented in tables, though
occasionally in the text, but in either case
usually in summarised form only (e.g. means and standard deviations).
Table 2. The flow rates of the manipulated patches, and mean simultaneous number
and turnover (number of different males per day) of territorial males on
experimental patches. (Values in parentheses are standard errors for each mean.)

Raw data may be appropriate if there are very few data, or you need to discuss
the values of specific data
points - but this is rare. Don't include big tables of your raw data. If it is important to include the raw
data (usually only the case if the data set may be of use to others as a basis for further analyses) they can
go in as an appendix.
Statistical summaries
- the results should be where most or all of the statistical results appear. There are
three places to include summaries of statistics:
1. In the text ....
The mean flow rate in patches of weed continuously occupied
and defended by males was
significantly greater than that for unoccupied patches (
t
=2.73, d.f.=28,
p
<0.05)
(Figure 1).
2. In figure legends ....
Figure 2. The relationship between flow rate and the number of oviposition events for
18 patches at the main study site (r=0.57, n=16, p<0.05).
3. In tables (if there are large numbers of tests to present which would clutter the text), e.g.
if you have an analysis involving 10 regressions of the same kinds of variables (e.g. body
weight and heart rate) for a number of different taxa, then it may be convenient to
summarise the slopes, intercepts and significance of the relationships
in a table rather
than trying to put all ten in the text.

NB - If you do a standard statistical test by hand, you do not include the working of the test in the paper -
just the result.
