Analysis of Research Results
In order to test the effect of agricultural cultivation on water quality, an experiment was conducted that looked at the amount of phosphorous in streams adjacent to agricultural fields of different sizes. The distances chosen were of range from 100 meters to 500 meters from the stream. Then the amount of phosphorous found was recorded for analysis. The analysis is done on a scatter plot, a bar graph, and a table. ANOVA analysis was carried out to find out the p-value of the data collected.
Results from the scatter plot are as below.

Average Phosphorous (mg/l)
From the scatter plot we find that the further away the area is from the stream, the more phosphorous can be found. From the scatter plot and the close relationship it can be concluded from the trend line, and also be said that the relationship is linear.
The p-value of the data gave a value of 0.02. At 5% confidence interval, a p-value of 0.02 is found to be significant. However, at 1% confidence, a p-value of 0.02 will not be considered significant. Considering the analysis done, the p-value is then not significant.
In order to test the effect of agricultural cultivation on water quality, an experiment was conducted that took five samples in each stream to look at the amount of phosphorous in streams adjacent to agricultural fields at different distances from the streams. These samples were taken at, 100 meters, 300 meters and 500 meters away from the streams. The graph and table below show the analysis carried out on the data obtained from this experiments.

Average Amount of Phosphorous
The graph above shows data collected from the five samples. It also lists the averages from the samples that are 100 meters, 300 meters and 500 meters from the streams. It was realized that the further the sample was from the stream the more phosphorous was available. In the samples 500 meters away there was more phosphorous than in the samples 100 meters from the stream. It can be then inferred that phosphorous from the samples nearer the stream had been eroded to the streams. The data in the experiment yielded a p-value of 0.001. At 1% confidence interval, the p-value of 0.001 is then significant in the analysis.
