A company wants to analyze sales data to understand which product, through which channel, and when it has been sold. The dataset includes four variables, including product name (e.g., A, B, C), purchase channel, the date of purchase, and Customer ID.
In terms of granularity, do you think the data is granular enough to allow the company to do the sales analysis?
a. Yes. The dataset is fine enough to do analysis.
b. No. The dataset is coarse, so the company cannot do analysis.
