Final answer:
The level of measurement for the top five books on a bestseller list is the ordinal scale, as the data provides an ordered ranking of books based on sales.
Step-by-step explanation:
The question pertains to identifying the level of measurement for a dataset, specifically the top five books on a bestseller list from the previous year.
The levels of measurement include nominal, ordinal, interval, and ratio. In this case, the bestseller list represents an ordinal scale, as the ranking of books indicates an order of precedence or superiority, with the top book selling the most copies, and so on.
The data does not determine the exact differences in sales between each book (interval) or the total sales (ratio), but simply ranks them, which is characteristic of ordinal data.
