1. The user is asking if "total sale data" refers to the whole month's net merchandise value (NMV). 2. To clarify, "total sale data" typically means the sum of all sales transactions over a specified period. 3. If the period is a month, then yes, it would mean the total NMV for that entire month. 4. NMV is the net value of merchandise sold, usually after returns and discounts. 5. So, total sale data for a month = sum of all NMV values for each day in that month. 6. If you want to calculate or analyze this, you would sum daily NMV values: $$\text{Total NMV} = \sum_{i=1}^{n} \text{NMV}_i$$ where $n$ is the number of days in the month.
