Range = 129 - 123 = 6
To find the interquartile range, we first need to find the first quartile (Q1) and the third quartile (Q3).
To find Q1, we need to find the median of the lower half of the data. The lower half of the data (when ordered) is 123, 125, 125. The median of this lower half is (125 + 125) / 2 = 125.
To find Q3, we need to find the median of the upper half of the data. The upper half of the data (when ordered) is 126, 127, 127, 128, 128, 129. The median of this upper half is (127 + 128) / 2 = 127.5.
So, Q1 = 125 and Q3 = 127.5
Interquartile Range (IQR) = Q3 - Q1 = 127.5 - 125 = 2.5
Therefore, the interquartile range is 2.5.
