1. The document discusses using groups to analyze data through parallel processing. It describes an example where a man buys and sells a horse named Harry, making a total profit of $20. 2. When the same mathematical problem is presented about a man's profits from buying and selling a horse and pig, people are more likely to get the right answer because it is framed differently than the original horse problem. 3. The document recommends using parallel processing when analyzing problems in groups - having each person solve the same problem independently before discussing together. It also advises stating problems in different ways to solve them.

2. “A man bought a horse named Harry for $60 and sold him for $70. Missing Harry, he bought him back for $80. Finally, he sold Harry for $90. How much money did he make in the horse business?” Solve individually (usually half the people get this correct). Spend 2 minutes. Adapted from AdPrin.com 2 The Horse Business

3. The Animal Business “A man bought a horse named Harry for $60 and sold him for $70. He also bought a pig named Pete for $80 and sold him for $90. How much money did he make in the animal business?” Did your answer differ from that in the horse business? Why?

4. The answer for the horse business is $20. Some people say $10, and $30 comes up also. In a group someone nearly always has the right answer. If people solve this individually and then and discuss it, the group solutions are correct for the vast majority of groups. Now to the “animal business” question. Mathematically, it is the same problem, but nearly everyone gets the correct answer. This is because the horse question leads them astray. Advice for doing analyses with groups: 1. Use parallel processing (each person solves the same problem independently), then check with each other and discuss it. 2. State the problem in different ways and solve those problems.

5. Based on this exercise, write a small application step for yourself, and set a deadline, preferably within one week. If you are working with someone else, share your application plan and the results of your application. For example, ask someone to check any important analyses in a report that you are currently working on. Adapted from AdPrin.com
