Optibrium

The quality of two compounds can be compared using the scores for those compounds. However, as a rule of thumb, one cannot differentiate between those compounds unless their scores differ by more than the sum of their standard deviations. One approach to visualizing whether compounds can be confidently differentiated is to plot a graph as shown to the right. In this figure the compounds are plotted in order of decreasing priority along the x-axis and their scores, with error bars illustrating the standard deviation of the scores, on the y-axis. In this example, we can clearly see that there are groups of compounds that can be confidently separated in terms or their likelihood of success, but within these groups the available data does not distinguish between compounds.
