Selected Answer: D

D. A column chart would show which site has the highest average. There's no additional dimensionality that would necessitate a scatter chart. Moreover, the outliers for site B1 would make a scatter plot difficult to read. I first checked ChatGPT, it agreed with me. Then, I built the table myself and played with building the charts in Excel. A column chart is far easier to read and correctly shows that B1 has the highest sales average per customer.

C. A scatter chart would allow you to visualize the relationship between sales volume and average sales per customer for each site. Each point on the scatter chart would represent a site, with the x-axis representing sales volume and the y-axis representing average sales per customer. This chart type is effective for identifying patterns and outliers in the data and can help determine which site is providing the highest sales volume per customer.
