Question

mr. higa places two bins of colored tiles in front of his classroom. each bin contains 200 tiles. he challenges students to predict the number of orange tiles in each bin. to help, he lets each student choose a random sample of 10 tiles from each bin.
the dot plots show the sample results from all the students. what do you notice about the data sets?
the centers look very different, but the spreads look about the same.
the centers and the spreads look very different for the two bins.
the centers and the spreads look about the same for both bins.
the centers look about the same, but the spreads look very different.

Explanation:

The dot plots for Bin A and Bin B show that the central tendency (center) of the number of orange tiles per sample differs noticeably (Bin A’s data clusters more around higher values than Bin B’s), but the range/spread (from ~1 to ~7 for both) appears similar.

Answer:

The centers look very different, but the spreads look about the same.
