I have a data set where individuals are given a percentage of disease severity 0-100%. I want to find means and compare groups in graph builder, but JMP treats my percentages as nominal data since they are rounded to the nearest 5%. I cannot change the data type to continuous because that option is grayed out. What should I do differently so I get accurate means of percentages for all the reps of a single treatment type? When I graph the data, percentages (y axis) are not in order and the means are not correct for each group.
