Question

The box-and-whisker plots show data for the test scores of four groups of students in the same class. Which plot represents a group with a median grade below 65?

A. box-and-whisker plot aA number line is shown with numbers labeled from 0 to 100 with a step size of 5. A box-and whisker plot is shown above the number line. The box-and-whisker plot has dots above the numbers 38, 60, 75, 95, and 97. A line segments connects the dots above 38 and 60, and another line segment connects the dots above 95 and 97. A rectangle is shown above the number line with the dot above 60 on its left edge and the dot above 95 on its right edge. A vertical line through the dot above 75 divides the rectangle into two parts. Note that the numbers 38 and 97 are best guesses from reading the number line.
B. box-and-whisker plot bA number line is shown with numbers labeled from 0 to 100 with a step size of 5. A box-and whisker plot is shown above the number line. The box-and-whisker plot has dots above the numbers 23, 33, 70, 78, and 96. A line segments connects the dots above 23 and 33, and another line segment connects the dots above 78 and 96. A rectangle is shown above the number line with the dot above 33 on its left edge and the dot above 78 on its right edge. A vertical line through the dot above 70 divides the rectangle into two parts. Note that the numbers 23, 33, 78, and 96 are best guesses from reading the number line.
C. box-and-whisker plot cAt the bottom of the image, a number line shows the numbers 0 through 100 with a step size of 5. There are dots above the approximate numbers 40, 58, 60, 81, and 96. A horizontal line segment connects the dots above the numbers 40 and 58, and another horizontal line segment connects the dots above the numbers 81 and 96. A rectangular box is shown above the number line with its left side passing through the dot above the number 58 and its right side passing through the dot above the number 81. A vertical line segment passing through the dot above the number 60 separates the box into two parts.
D. box-and-whisker plot d

Answer 1

The correct answer is A. Box-and-whisker plot A represents a group with a median grade below 65, as the median line is below 65 and the majority of the data is below the median. The other plots have a median line above 65.
