Count the number of data points that do not overlap. For example, assume there are 10 pieces of data that do not overlap.
Count all the data points. In the example, assume there are 20 pieces of data in all.
Divide the non-overlapping data points by all the data points to calculate the percentage of non-overlapping data points. In the example, 10 divided by 20 equals 0.5. If you multiply this by 100, it will convert it into the percentage form of 50 percent.
