Cell numbers can be converted to probits that are used to compare the degree and timing of synchronized cell cultures. Data from synchronous cultures of Chlorella pyrenoidosa have been analyzed by this method by means of a readily available computer program. The method can be used with any biological system that generates normal sigmoidal data.
