Answer:
3
Step-by-step explanation:
1, 1, 3, 4, 4, 5, 5, 5, 6, 7, 9
Median: 5
Lower quartile: 3
Upper quartile: 6
Interquartile range: 6 - 3 = 3
The interquartile range (IQR) of the data set 1, 1, 3, 4, 4, 5, 5, 5, 6, 7, 9
would be 3.
IQR(interquartile range) is the difference between the third and first quartile.
Range = Maximum value of the data set - Minimum value of the dataset
The following data points represent the number of classes that each teacher at Broxin High School teaches.
