I am trying to show the normal distribution of two sets of data. My goal is to see if dataset 1 differs to dataset 2 (the dataset is total eroded area in m2). When i make normal distribution curves, i am aiming to fix or understand these problems
- firstly im not sure how to interpret these negative values as total eroded area (my variable) cannot be negative
- secondly im not sure what these greater than 1 y values mean
Dataset 1 is 0.180,0.063,0.65,0.43 and Dataset 2 is 0.148, 0.106, 0.39, 0.32 and the resulting normal distribution graph (based on the mean and standard deviation) is shown below.
