In a boxplot, what percentage of data lies within the box from Q1 to Q3?

Explanation:
The part of the box between the first and third quartiles contains the middle half of the data. Q1 is the 25th percentile and Q3 is the 75th percentile, so 25% of the data lies below Q1 and 25% lies above Q3. The interval from Q1 to Q3 therefore includes the remaining 50% of the data. So, half of the data lie within the box.
