The Interquartile Range (IQR) is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). First, we need to arrange the data in ascending order: 60, 63, 65, 65, 67, 69, 69, 73, 74, 77, 79. For this data set, Q1 (the median of the first half) is 65, and Q3 (the median of the second half) is 74. Therefore, IQR = Q3 - Q1 = 74 - 65 = 9.
