The IQR is a measure of spread that is less affected by outliers compared to the standard deviation. While the standard deviation measures the spread of data from the mean, the IQR measures the spread from the median, making it a more robust option for skewed data.
Calculate IQR: Understanding Interquartile Ranges in Data Analysis
As data analysis becomes increasingly crucial in various industries, organizations are seeking more efficient and accurate methods to interpret and visualize their data. One of the essential concepts in data analysis is the interquartile range (IQR), which is gaining attention in the US due to its simplicity and effectiveness in understanding data distribution. In this article, we will delve into what IQR is, how it works, and its applications, as well as common questions, opportunities, and misconceptions related to this concept.
What are the limitations of IQR?

This topic is relevant for anyone working with data, including:
The IQR is a measure of the spread of data, calculated by subtracting the 25th percentile (Q1) from the 75th percentile (Q3). It provides a better understanding of data distribution than the standard deviation, as it is less affected by outliers. To calculate IQR, arrange the data in ascending order and find the median (Q2). Then, locate the 25th and 75th percentiles, which split the data into four equal parts. The IQR is the difference between Q3 and Q1.
The IQR offers several opportunities for data analysts, including:
