What are some examples of IQR and range in statistics?
The Interquartile Range (IQR) measures the middle 50% of data. For example, if you have the data set: 1, 3, 5, 7, 9, the IQR is 5 - 3 = 2.
Can you explain how to calculate the range?
Sure! The range is calculated by subtracting the smallest value from the largest value in a data set. For example, in the set 2, 4, 6, 8, the range is 8 - 2 = 6.
What does a high IQR indicate?
A high IQR indicates that there is a large spread in the middle 50% of the data, suggesting more variability.
Can you give me a real-world example of IQR?
Certainly! In a class of students' test scores, if the scores are 55, 60, 65, 70, 80, the IQR helps us understand the score distribution among the middle-performing students.
