Given:
Students from Williams Middle School are also recycling aluminum cans. The data for the numbers of cans brought in each school day for a month were divided by quartiles and summarized in the box plot.
We need to determine the Median, Interquartile range and Range.
Median:
The median is the middle value of the given set of data.
From the box plot, it is obvious that the median line is at 18.
Thus, Median = 18
Hence, the value of the median is 18.
Interquartile range:
The interquartile range is can be determined by finding the difference between the ends of the box in the box plot.
From the box plot, we have;
Interquartile range = 20 -16
Interquartile range = 4
Hence, the value of the interquartile range is 4.
Range:
The range can be determined by subtracting the highest and the lowest value in the given set of data.
From the box plot, the range can be determined by subtracting the ends of the line.
Thus, we have;
Range = 28 - 10
Range = 18
Hence, the value of the range is 18.
