Question

Mrs. Casillas represented the scores from her math classes on the box plots below. which statement below is best supported by the information in the box plots?which statement bus best s supported by the information in the box plots?A) the interquartile range of the data for class 2 is greater than the interquartile range for the data for class 1.B) the minimum test score for class 1 is less than the minimum test score for class 2C) the range of the data for class 1 is less than the range of the data for class 2D) the median of the data for class 1 is greater than the median of data for class 2.

Answer 1

From the box plot presented we can check that the median value for both classes are equal. Both reside in 85%. For this reason, option d) is false.

We also see that the distance from the biggest score to the lower one for class 1 is (100 - 70) = 30, while for class 2 is (95 - 70) = 25. From this, we can say that c) is false.

Both representations, for class 1 and 2, show the lower score as 70%. For this reason the option b) is also false.

We can see the points of the 'interquartile' for the class are at 92 and 77, which results in a more dispersed distribution. For this reason, it is reasonable to say that the range of this data is greater than for class 1. From this, we conclude that option a) is the one that best supports the box plots.
