A pharmaceutical company conducts a clinical trial to test the efficacy of a novel cancer therapy. The company randomly selects 15 subjects from a larger population of patients with relapsed and refractory diffuse large b-cell lymphoma. Each subject is randomly assigned to one of three treatment groups. Within each treatment group, subjects receive a different dose of the new medication. G1 subjects receive 0mg/day, G2 subjects receive 50mg/day and G3 subjects receive 100mg/day. The doctors measure the lesion sizes in each subject. Results are as below.
