Anderson (1999) was interested in the effects of attention load on reaction time. Participants in her study received a dual-task procedure in which they needed to respond as quickly as possible to a stimulus while simultaneously paying attention to the sounds of spoken words. She recorded reaction time (in hundreds of milliseconds). Below are data like those observed by Anderson: \(3, 4, 4, 4, 5, 6, 8, 12, 20, 25\) a. Find the mean, median, and mode. b. Based on the relative values of those statistics, what is the shape of the distribution? c. Anderson (1999) reported median reaction times. Why?
