The interquartile range (IQR) is a measure of statistical dispersion, which is defined as the difference between the 75th percentile (Q3) and the 25th percentile (Q1) in a dataset.
To find the interquartile range of the numbers given: -5, -10, -10, -2, -10, -5, -2, -10, -10, -5, we first need to arrange the numbers in ascending order: -10, -10, -10, -10, -10, -5, -5, -5, -2, -2.
Q1 = Median of the first half = (-10, -10, -10, -10, -10) = -10
Q3 = Median of the second half = (-2, -2, -5, -5, -5) = -5
IQR = Q3 - Q1 = -5 - (-10) = 5
Therefore, the interquartile range of the given numbers is 5.

IQR = Q3 - Q1 = -5 - (-10) = 5
Therefore, the interquartile range of the given numbers is 5.
