Which metric best measures the volume of store activity independent of revenue?

• A. Average sale
• B. Total transactions
• C. Sales per hour
• D. Units per transaction

Answer: (B)

To gauge how busy a store is without tying it to how much money is being made, the best metric is the total number of transactions. Each transaction represents a completed sale, so counting them directly reflects customer activity and store traffic. It measures volume independent of price changes or promotions because it doesn’t consider how large or small each sale is—just that a purchase occurred.

Why the other metrics aren’t as good for this purpose: average sale combines revenue and volume into a dollar amount, so it can rise or fall with pricing or discounting rather than with how many customers came in. Sales per hour traces revenue flow over time, which mixes price effects with activity and doesn’t isolate how many transactions occurred. Units per transaction looks at how many items are bought per sale, which can vary with promotions or product mix and doesn’t directly measure how many customers completed purchases.
