Common questions
Why it's trending now
IQR is primarily used for continuous data, but it can also be applied to categorical data with ordinal scales. However, its effectiveness depends on the distribution of the data and the number of categories.
The IQR is not affected by outliers

Why it's gaining attention in the US
IQR can be used for small datasets, but its effectiveness depends on the number of observations and the distribution of the data.
The IQR and standard deviation are both measures of variability, but they differ in their approach. The IQR is more robust and less affected by outliers, while the standard deviation is sensitive to extreme values.

Common misconceptions
This is not necessarily true. The IQR can be larger than the standard deviation, especially if the data has a skewed distribution.
What is the difference between IQR and standard deviation?
Can IQR be used for all types of data?
- Data analysts and scientists
- Practice calculating and interpreting IQR using real-world datasets
- Business professionals
- Measuring variability and spread
- Detecting changes over time
- Sort your data in ascending order.
- Social scientists
- Using IQR in combination with other measures, which can lead to incorrect conclusions
- Comparing datasets and identifying trends
- Researchers
How it works
The IQR is a measure of the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. To calculate the IQR, you need to follow these steps:

The IQR can be used to determine the spread of the data and detect outliers. A small IQR indicates a narrow range, while a large IQR suggests a wider range. Outliers can be detected by comparing the data points to the IQR.
No, the IQR and range are not the same. The range is the difference between the maximum and minimum values, while the IQR is a measure of the variability between the 25th and 75th percentiles.
Is IQR the same as the range?
While the IQR is more robust than the standard deviation, it is not completely immune to outliers. Large outliers can still affect the IQR, especially if they are close to the 25th or 75th percentile.
