which information source would be considered secondary data for research on how to improve the sales of an existing product?\nmultiple choice\ndata from the census bureau website\nproduct sales figures\ninterviews with prospective users about the product\nrecent survey results about how consumers use the product\nfeedback from sales reps on the product
Answer
Brief Explanations:
Secondary data is information that has already been collected by others. The Census Bureau website data is collected for a general population - related purpose and not specifically for improving the sales of this existing product. Product sales figures, interviews with prospective users, recent survey results about product use, and feedback from sales reps are all data directly related to the product and its sales (either from the company's own records or direct interaction with relevant parties for the product).
Answer:
data from the Census Bureau website
