The interquartile range (IQR) is a measure of the spread or dispersion of the middle 50 percent of data. In this case, the IQR is equal to 5.

The interquartile range (IQR) is a measure of the spread or dispersion of the middle 50 percent of data. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). In this case, the IQR is equal to 5, therefore the correct answer is Option C.
