mr. wills keeps markers in two boxes. each box has 80 markers of different colors. the box plots show the number of blue markers found in random samples of 20 markers from each box. what do you notice about the data sets? the centers look about the same, but the spreads look very different. the centers look very different, but the spreads look about the same. the centers and the spreads look about the same for both boxes. the centers and the spreads look very different for the two boxes.

Explanation:

• Center: The median (center of a box - plot) for both Box A and Box B appears to be around the same value. In a box - plot, the line inside the box represents the median. Visually, the position of these median lines is similar for both box - plots.
• Spread: The spread of a box - plot is indicated by the length of the box (inter - quartile range, IQR) and the whiskers (range). The length of the boxes (IQR) and the whiskers (range) for Box A and Box B look very different.

Answer:

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