-Based on the above chart, what was the inter-quartile range of marks (approximately)?

Quizplus · Accepted Answer

The interquartile range (IQR) is the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of the data. Without the specific chart, a general explanation is that the IQR measures the middle 50% of the data, indicating the spread or variability within the middle half of the dataset. Given the options, if the correct answer is B) 14%, it suggests that the middle 50% of the marks spread across approximately 14 percentage points.
