Coontie Plant Height and Gender Density

Growing in the Shade compared to in the Sun

Research Question

What affect does growing in the shade compared to growing in the sun have on Hight and on gender density?

Data Collection

Data was collected at New College of Florida infront of the Academic Center. The height and gender of 20 Coontie plants growing in the sun and 20 Coontie plants growing in the shade were collected. The plants were measured by height from the base of the plant to the tallest point of the plant (to the leaf tip). Total population size of 40.

Variables

Explanatory – Sun and Shade dwelling plants

Response – Hight of the plant and the density of each Gender in the given area

Histogram

Figure 1

Height frequency of plants that grow in the sun and in the shade. Sample size includes 20 Shade and 20 sun dwelling plants for a total of 40 plants.

The histogram shows that the plants that grew in an environment with more sun had a higher frequency of plants that were taller. Plants that grew in a more shaded environment did not have as high of a frequency of taller plants.

Conclusion

In conclusion, it seems that the plants that grow in the sun seem to have a higher frequency of taller plants. In regard to gender, there seems to be an even distribution of Male (18) and Female (22). Female plants seem to have a higher density than males in the sun based on the data but could be proven to be different with a larger sample size. The data also shows that the Male plants have a higher frequency of taller plants in the Sun, while Female plants have a higher frequency of taller plants in the Shade.
