Quantal Data: When the response for an individual unit (well, animal etc) is a binary value, such as alive / dead, or response / no response, the data are treated as quantal. The responses are assumed to follow a binomial distribution within each dose group.  This assumption is required for the calculations of confidence intervals and the p values resulting from statistical tests.
