The dot plot gives the diameter, to the nearest inch, of each sea star in a group of tide pools. The number of dots above a given diameter represents the number of sea stars with that diameter, to the nearest inch. There 16 are 6 dots above inches. Therefore, 6 sea stars had a diameter, to the nearest 16 inch, of inches. Choice A is incorrect and may result from calculation or conceptual errors. Choice C is incorrect. This is the number of sea stars with a diameter, to the 17 16 nearest inch, of inches, not inches. Choice D is incorrect.
