What are the differences between IQR and range?
An example of an AI chatbot conversation about the differences between IQR and range in statistics.
What are the differences between IQR and range?
The range is the difference between the maximum and minimum values in a dataset, while IQR (Interquartile Range) measures the spread of the middle 50% of the data.
Can you explain how to calculate both?
Sure! To calculate the range, subtract the minimum value from the maximum value. For IQR, first find the first quartile (Q1) and the third quartile (Q3), then subtract Q1 from Q3.
Why is IQR considered more robust than range?
IQR is more robust because it is not affected by outliers, while the range can be significantly influenced by extreme values.
Can you give an example of when to use IQR instead of range?
Certainly! If you have a dataset with outliers, like income data, using IQR will give you a better sense of the central tendency without being skewed by those outliers.
