A lаrge e-cоmmerce cоmpаny wаnts tо determine if a new, ergonomically designed handheld scanner improves the picking speed of its warehouse associates. To test this, the company conducts an experiment over one week in a single distribution center that has 50 associates working on any given day. The experimental procedure is as follows: Each morning, the 50 associates on shift are randomly assigned to one of two groups. Half (25 associates) receive the new ergonomic scanner (the "treatment" group), and the other half (25 associates) continue using the old scanner (the "control" group). For the rest of their shift, the associates pick orders, and the system records the time it takes to pick each individual item. At the end of the week, analysts plan to compare the average pick time per item between the two groups. In the design of this experiment, what is the correct experimental unit?
A glоbаl electrоnics mаnufаcturer is evaluating twо shipping routes for a critical microprocessor sourced from a single factory in Taiwan to its assembly plant in Mexico. The company's primary goal is to ensure a highly predictable supply chain to support its Just-in-Time (JIT) manufacturing system, where transit time consistency is more critical than the absolute lowest average transit time. The company analyzes the transit time data (in days) from the last 50 shipments for each route: Route A (Direct Air Freight): This is a premium, direct-to-destination route. The data shows transit times are tightly clustered, but on two occasions, shipments were held in customs for an extensive period due to random high-level inspections, creating two significant outliers (e.g., 15 and 18 days, when most shipments took 3-4 days). Route B (Sea-Air Combination): This is a standard, multi-leg route. The transit times are naturally longer and more spread out than Route A's typical times, but the data contains no extreme, unexpected outliers. The average transit time is higher than Route A's average. Given the company’s priority for predictability and the nature of the data, which measures should the logistics analyst use to provide the most robust and insightful comparison of the two routes' transit time reliability?
