Ssa- your shoes example uses a model far too simple to develop a useable forecast. But given an appropriate amount of data a qualified statistician can forecast trends very accurately. You like your weather forecast right? You like it when you call a company and get connected to customer service rep quickly right? Operations management and weather both rely a great deal on statistics to make forecasts, and wouldnt bother if it didnt help predict the future. If you are interested in how it works, go ahead and study statistics. If youre like me and just like having others do the maths for you, trust them to do their job 🙂
