As simple, example values, you compare a salary of $10,000 earned by a part-time shipping clerk, a salary of $100,000 earned by a manager, and the CEO’s $1,000,000 compensation package. Why might the average of these values be a misleading sum- mary? What would the logarithms of these three values be?
