Question

8, 3, 5, 5, 4, 7 Find the median, lower quartile, and upper quartile of the set of data. Use the median, lower quartile, upper quartile, lowest value, and highest value of the set to construct a box-and-whisker plot on your own sheet of paper. Use the box-and-whisker plot to find the range and the interquartile range of the set of data.

Answer 1

Median: 5

Lower quartile: 4

Upper quartile: 7

Lowest value: 3

Highest value: 8

Box plot below

Explanation:

When making a box plot, you plot the lowest value and the highest value. You make a box going from the lower quartile (in this case it's 4) to the upper quartile (7). You put a point on the median for the overall set of numbers, and you're done!
