The interquartile range (IQR) is a measure of the dispersion of the middle 50% of the data. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
Q1 = $11,000
Q3 = $24,000
IQR = Q3 - Q1
= $24,000 - $11,000
= $13,000
Therefore, the interquartile range of the data is $13,000.
Q1 = $11,000
Q3 = $24,000
IQR = Q3 - Q1
= $24,000 - $11,000
= $13,000
Therefore, the interquartile range of the data is $13,000.
