## how to find the range of a box plot The range is the simplest measurement of the difference between values in a data set. To find the range, simplysubtract the lowest value from the greatest value, ignoring the others. Where is the Iqr on a box plot? The 鈥渋nterquartile range鈥? abbreviated 鈥淚QR鈥? is just the width of the box in the box-and-whisker plot.

• ### How do you make a box plot with interquartile range?

• To make a box plot, we draw a box from the first to the third quartile. Then we draw a vertical line at the median. Lastly, we draw 鈥渨hiskers鈥?from the quartiles to the minimum and maximum value. The interquartile range, often abbreviated IQR, is the difference between the third quartile and the first quartile.

• ### What is a box plot in statistics?

• A box plot is a type of plot that displays the five number summary of a dataset, which includes: To make a box plot, we draw a box from the first to the third quartile. Then we draw a vertical line at the median. Lastly, we draw 鈥渨hiskers鈥?from the quartiles to the minimum and maximum value.

• ### How do you graph a box plot in Excel?

• To graph a box plot the following data points must be calculated: the minimum value, the first quartile, the median, the third quartile, and the maximum value. Once the box plot is graphed, you can display and compare distributions of data. Use the following information to answer the next two exercises.

• ### How do you find the first quartile on a box plot?

• The outer lines of the IRQ show the first and third quartiles, so if you are looking at the lower half of the data, then the edge of the IRQ, where the IRQ and whisker meet, is approximately one half of the lower half of the data. In other words, the first quartile is the median of the lower half of the data. What are box plot whiskers?
