Find The Median Of The Data In The Box Plot Below. The box-and-whisker plots show the speed in miles per hour for each of 10 fish and 10 mammals. The whiskers small lines go from each quartile towards the minimum or maximum value as shown in the figure below.
A vertical line that goes through the box is the median. Then the middle data value is the 5 th value counting from either the left or the right. The IQR describes the middle 50 of values when ordered from lowest to highest.
To graph a box plot the following data points must be calculated.
Find the interquartile range IQR of the data in the box plot below. The second quartile Q2 sits in the middle dividing the data in half. The horizontal line inside the box is the median. In this case 4 and 5 are in the middle in the middle of 4 and 5 is 45.
