        Designing Experiments | Against All Odds: Unit 15

        Examine two case studies that reveal how scientists design experiments with sample sizes and control groups in this video from the Against All Odds statistics series. A study of a coral reef ecosystem and a study of patients taking pain relievers for osteoarthritis show the precision in which researchers design experiments. Host Pardis Sabeti demonstrates the importance of carefully desinging experiments with control groups, placebos, sample size, and non-biased instruction.
