Hey! I need you to create a final report that analyzes, concludes, and evaluates this data in accordance with the requirements written below.
Quadrat location | Number of plants counted (Clover) | (Optional second plant count) (Dandelion) |
1 | 376 | 2 |
2 | 218 | 15 |
3 | 112 | 4 |
4 | 279 | 3 |
5 | 23 | 10 |
6 | 118 | 6 |
Average plant count. . . | 187.6 | 6.6 |
My quadrats surface area (m2) | 0.359m2 | 0.359m2 |
Average number of plants per m2 | 522.6 clovers/m2 | 18.4 dandelion/m2 |
Total Field Area | 10 836.62 m2 | 10 836.62 m2 |
Conclusion
-
The conclusion will be the estimated number of plants per square metre. Looking at your numbers and at the standard deviation, you could comment on the variability of the data. You could also comment on whether the distribution of the species you studied is even or clumped. It will probably be difficult to compare your results with quantitative results from other scientists because they will probably have studied a different field in a different part of the world with a different plant species. However, you might find some published data about the number of plants of your chosen species that occur per square metre.
Evaluation
There are many sources of error to explore in this lab. Here are some possibilities:
-
misidentification of plants, because some species look similar
-
accidentally counting the same plant twice within a quadrat
-
sometimes two plants can grow so close together that they look like one
-
tall grass or other vegetation might hide smaller individuals of the species being counted
-
by bad luck or human error, the randomness of the sampling might not be so random and certain parts of the field might be sampled more often than other parts of the field.
Instructions for final report:
State the intended purpose of this investigation. Write a brief introductory paragraph describing the actual process you followed. Identify the variables you studied. Include your data table. Include a sample calculation for any step of your analysis. Write a conclusion...make sure you tie this conclusion back to the purpose of the investigation. Evaluate the validity of your investigation, include sources or error, statistical reliability of your quadrats, etc. Always include suggestions for future research.
-
Analysis: (some is in the data table: areas, averages) BUT you still need to do the standard deviation calculation.
-
Conclusion (must ALWAYS relate back to the purpose!!!)
-
Evaluation (separate OR combined with the conclusion) address quality of data and thus the quality of the conclusions. Sources of error (both random and systemic)
