The IQR (Interquartile Range) is a measure of statistical dispersion, or in simpler terms, it measures the spread of the data. In this case, since the IQR is 2.5 hours, it means that the difference in the number of hours spent on the project between the 75th percentile and the 25th percentile of students is 2.5 hours. This tells us that for the middle 50% of students, the range of hours spent on the project is 2.5 hours.
