The effect of various
concentrations of Chemical X
on the height of tomato plants
is summarized in Table 9.3.
Table 9.3 show the effect of
various concentrations of
Chemical X on the growth of
tomato plants.
The mean height of plants is
grown at 10% X (18.1cm) was
higher than the control
(15.3cm). At higher
concentrations of Chemical X,
mean plant height was reduced,
e.g., 10.5cm at 20% X and
6.0cm at 30% X.

X, and 30% X. As the
concentration of Chemical X
increased, the range in plant
height decreased.

would decrease as
concentration of Chemical X
increased. Below 10% X little
growth differences were
observed; however, at higher
concentrations, growth was
severely hindered.
The mean height of plants
decreased as the concentration
of Chemical X increased, e.g.;
18.1cm, 10.5cm, 6.0cm.
Interestingly, greater mean
height was observed at 10% X
(18.1cm) than in the control
group (15.3cm).
The control group, 10% X
group, and 20% X group
showed similar variations in
height. Less variation occurred
at 30% X (Range = 4cm.)
At 10% X, growth was not
slowed. Above 10% X, plant
growth was progressively
slowed; thus, the hypothesis
was partially supported that
growth of plants would
decrease ass concentrations of
Chemical X increased.

2. Write sentences comparing the measures of

The influence of Chemical X on the health of
tomato plants is summarized in Table 9.5.
(Describe the table.)
When plants received 10% or less chemical X,
they remained healthy. At concentrations of
20% X or above, plant health deteriorated.
The greatest variation in plant health was at
20% X, where 4 healthy and 6 unhealthy plants
occurred. At concentrations below 20% X,
plants were predominantly healthy; at 30% X,
the majority of plants were unhealthy.
The data on plant health supported the
hypothesis that higher concentrations of
Chemical X would adversely affect plant
growth.

4. Write sentences stating how the data
support the hypothesis.

Questions

5. Write a topic sentence stating the

reference to tables and graphs.
6. Write sentences comparing the measures of
central tendency of the groups (medians).
Leaf quality of plants exposed to various
concentrations of Chemical X is summarize in
table 9.6. (Describe the table.)
High quality leaves, with a rating of 4, were
typically found on both control and 10% X
plants. At higher concentrations, leaf quality
deteriorated, with leaf quality ratings of 2 and
1 on plants grown with 20% X and 30% X.
The greatest variation in leaf color occurred at
10% X where leaf quality ratings of 4, 3, and 2
were assigned. No variation occurred in the
control; all leaves received a rating of 4. At
20% X and 30% X, the plants fell into only
two categories, 3 and 2, or 2 and 1.
Data on leaf quality supported the hypothesis
that Chemical X would impede plant growth.

Conclusion
(This section of your paper will begin directly after your Data Tables & Graphs
section of your paper. You will put the answers to the following questions in
paragraph form. Below are some examples.)
Questions
Examples
1. What was the purpose of the experiment?
The purpose of this experiment was to
investigate the effect of various concentrations
of Chemical X on the growth of tomato plants.
At successively higher concentrations of
Chemical X, the mean height of the tomato
plants decreased and plant health and leaf
quality deteriorated. The mean plant height at
10% X (18.1cm), was greater than the control
(15.3cm), with plants exhibiting similar health.
More plants exhibited poor leaf quality in the
10% X group than in the control.
In general, the research data supported the
hypothesis that growth of the tomato plants
would decrease as the concentration of
Chemical X increased.
Although Crook and Bolton reported that
concentrations of 10% X were harmful to
radish plants, slightly reduced leaf quality was
the only indicator of an adverse effect in this
experiment.
Discrepancies in findings could result from
different plant species or methods of
application. In Crook and Bolton’s study the
solution was poured on both plant and soil,
whereas in this study the solution was poured
only on the soil.
Additional studies could be conducted to
determine the effect of Chemical X within the
0% - 20% range on both types of plants and
with different methods of application.
2. What were the major findings?
3. Did the data support the hypothesis?
4. How did your findings compare with other
researchers?
5. What possible explanations can you offer
for your findings?
6. What recommendations do you have for
further study and for improving the
experiment?
