I created a bar graph displaying the percentage of samples observed to have C. fulgida plants. I felt that a bar graph was the most appropriate way to display this data because the observations were stratified according to location within the field where observations were taken. When I collected this data, I recorded twenty samples in each stratification. I initially plotted the data according to the number of plots that had C. fulgida, but I then changed the Y-axis of the plot to percentage of sample units with C. fulgida. I felt that displaying the data as a percentage was more easily interpretable for a reader.
The outcome of my graph aligns with what was expected because the plot shows that the hill stratification has a higher percentage of plots with C. fulgida than the creekside stratification. This aligns with my hypothesis that location in the field influences C. fulgida because of differing soil moisture between locations. The figure I submitted will have to be displayed with an additional figure displaying that the hill stratification has drier soil than the creekside stratification for the relationship between soil moisture and C. fulgida to be understood.
