Figure 1. As soil moisture increases, height of Larrea tridentata increases. Soil moisture is given as a ‘reading’ from the garden moisture reader with a scale of 1 (driest) to 10 (wettest). Height is given in meters (m). The R² value of the graph is 59%.
Above is one of the graphs created from my data. As per my prediction, creosote plants that grew in soils with higher moisture levels tended to be taller than their drier counterparts. The graph was relatively easy to construct and interpret. Further regression analysis is needed to see if the line is truly statistically significant by analyzing the residual plots, but an R^2 value of 0.59 or 59% indicates that it is probable.
