The article discusses scientific experiments, focusing on different experimental designs. Randomized experiments, quasi-experimental design, prospective studies, and retrospective experiments are explored. The author notes that though many experimental designs are not used in high school science classes, they relate to a large proportion of experiments conducted by scientists and discussed in the media.
