How To Calculate the Five Number Summary

    The five number summary can only be calculated for numeric data. So any non-numeric columns will not be shown.

What is the Five Number Summary

 the five number summary is a tool to describe your data set.

It consists of the min, Q1, median, Q3 and the maximum values and your data. This calculator will find the five number summary for each the numeric columns in your data set.

The five number summary can also be visualized as a box plot. A box plot shows the mean, Q1, median, Q3 and maximum values as well.

If you want to see more detail about the spread of your data you can use a histogram. A histogram will show you how your data is distributed.  This is especially useful if your median is not halfway between your Q1 and Q3. This can indicate that you have a skewed distribution that might require further analysis.

How Do You Calculate Q1 and Q3

  1. Order your data from lowest value to largest value
  2. Find the value that is bigger than 25% of all other values. This is Q1.
  3. Find the value that is bigger than 75% of all other values. This is Q3.

What is Interquartile Range (IQR)

The interquartile range (IQR) is the difference between Q3 and Q1. You can find the interquartile range from your five number summary by getting Q3 and subtracting Q1. The interquartile range should always be positive because Q3 should always be larger than Q1.
