The interquartile range, IQR is given as 5
Third qartile, Q3 = 9
IQR = Q3 - Q1
5 = 9 - Q1
Q1 = 4
Therefore, the first quartile is 4.
In the boxplot drawn, Q1 is marked as 5, which is incorrect. It must be 4.

How do you find the standard deviation of a data set of numbers? I know the median, and the upper and lower quartile numbers. I am making a box plot and need to know how to graph that on a box plot as well. For example let us say the numbers are 1,2,3,4,5,6,7,8,9. How would you find the standard deviation?
