The interquartile range is a measure of where the “middle fifty” is in a data set, where the bulk of the values lies.
The interquartile range formula is the first quartile subtracted from the third quartile:

IQR of the Mid-Term
Step 1: Arrange the numbers in order

Step 2: Find the median

Step 3: Find Q1 and Q3
Q1 and Q3 are the median of the numbers before and after the median of the data set. Therefore, Q1 is the median of the first 5 numbers:

Q3 is the median of the last 5 numbers:

Step 4: Calculate the IQR

IQR of the Final
Step 1: Arrange the numbers in order

Step 2: Find the median

Step 3: Find Q1 and Q3
Q1 and Q3 are the median of the numbers before and after the median of the data set. Therefore, Q1 is the median of the first 5 numbers:

Q3 is the median of the last 5 numbers:

Step 4: Calculate the IQR

ANSWER
The data with the smallest IQR is the FINAL.
