These are the averages of the data we collected. We averaged all the numbers for each condition of sunlight, before and after.
|plot||Average bacteria # Before per cc^2||Average Bacteria# After per cc^2|
According to our data graph, the sunlight has no significant effect on the growth of bacteria and does not cause the population to decrease. However, when T-Testing the collected data, we found that there was a significant difference between the bacteria levels in the soil before we manipulated the amount of sunlight. After the manipulating the bacteria amounts in the soil were not longer significant.
Based on the P-values from the T-Testing something that happened during the manipulating of the sunlight, affected the bacteria in the plots. During our experiment, we experienced a heavy rain storm. We think that the rain may have affected the results, causing the bacteria amounts to no longer be significant.
|Before Sunlight Manipulating||plot number||P-Values||After Sunlight Manipulating||plot number||P-Values|
|negative control 0 (A)||vs. B||.06||negative control 0 (A)||vs. B||.209|
|negative control 0 (A)||vs. C||.02||negative control 0 (A)||vs. C||.224|
|negative control 0 (A)||vs. D||.03||negative control 0 (A)||vs. D||.189|
|negative control 0 (A)||vs. E||.04||negative control 0 (A)||vs. E||.302|
Conclusion: We found that the sunlight is not affecting the bacteria in site four.
