The relative response (p) is the number of responding individuals divided by the total number given a certain dose. 75, respectively. These numbers may be multiplied by 100 to give the percent response. We very often measure all-or-none symptoms (dead or alive, with tumor or without tumor, numbers of fetus with injury or normal ones) in toxicology. Such symptoms are not gradual. We then have to expose groups of individuals with different doses (D) and determine the number of responding individuals (r) and the relative number (p).
