1: A car mechanic is given a 1966 Mustang to fix. The owner's complaint is that the engine runs roughly, especially when the car is accelerating. The mechanic's first guess as to the source of the problem is that the fuel mix is too rich. After adjusting the fuel mix valve, the problem persists, so the mechanic then guesses that the sparkplug advance mechanism is faulty. Replacing the sparkplug advance mechanism (the diaphragm attached to the distributor) fixes the problem, and the fixed car is returned to the owner.

2: To determine the most effective sales strategy, consumer goods retailers sometimes do experiments. These experiments help the retailer understand how people decide what to purchase. For example, the retailer can change whether a product is displayed on a high or low shelf, or can change which products are displayed nearby. The retailer then analyzes these data, and changes their product displays so as to maximize sales.

3: A wildlife biologist is put in charge of designing a strategy to maintain a population of mountain lions in West Texas. The first action taken by this biologist is to determine whether population size is increasing or decreasing, while allowing current management practices to continue. By tagging animals and monitoring the population over 10 years, the biologist discovers that the population is declining at 3% per year.
