After a couple years driving your Jeep Wrangler, you notice that every time you hear a ticking from the engine, if you change your oil, the ticking stops. One day you notice the ticking, and you change your oil, but the ticking doesn’t stop. You take your Jeep to a service station, and the mechanic says you have a faulty cam sensor that is causing the ticking. Describe your own scientific method as it relates to the flow chart above.
