The range is the difference between the highest and lowest values in the dataset.
Range = 129 - 123 = 6
To find the interquartile range, we first need to find the first quartile (Q1) and the third quartile (Q3).
Q1 is the median of the lower half of the dataset, and Q3 is the median of the upper half of the dataset.
Arranging the dataset in ascending order: 123, 125, 125, 125, 126, 127, 127, 128, 128, 129
Q1 = median of (123, 125, 125, 125, 126) = 125
Q3 = median of (127, 127, 128, 128, 129) = 128
Interquartile range (IQR) is the difference between Q3 and Q1.
IQR = Q3 - Q1 = 128 - 125 = 3
Therefore, the range is 6 and the interquartile range is 3.
