To find the interquartile range, we first have to find the upper and lower quartile values. This task isn't as straightforward as you would think, as Wikipedia lists four methods and the R programming language implements nine different ways. 🙋 The 5 number summary calculator explains the up...
Q1 = 1st quartile or 25th percentileQ1 is the value below which 25 percent of the distribution lies, while Q3 is the value below which 75 percent of the distribution lies.You can think of Q1 as the median of the first half and Q3 as the median of the second half of the distribution....
7. How do you find quartile and interquartile ranges? The first quartile is the data point which marks the first 25% of the data. The third quartile is the data point which marks 75% of the data. The interquartile range is the difference between the first and the third quartile of the...
The interquartile range formula is the first quartile subtracted from the third quartile: IQR = Q3 –Q1. The IQR gives us a sense of the data’s spread around the median, excluding possible outliers. Therefore, the interquartile range is often more informative than the range for datasets that...

In order to find the interquartile range, you must first arrange the data from least to greatest. After that it would be easier for you to find the median. Once you found it, break up the medians left and right part into smaller parts equally. Find the difference of the numbers in...
