Find a five-number summary.Compute the interquartile range (IQR).Find outlier bounds.Interpret spread from a box plot.📚 Quick Recap
A box plot (or box-and-whisker plot) summarizes a dataset's distribution using five key numbers, making it easy to compare spread, center, and outliers at a glance.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1The five-number summary of 3,5,7,9,11,13,15 is:
2The IQR of that dataset is:
3If Q1 = 50 and Q3 = 75, the IQR is:
4The upper outlier bound is Q3 + ___ × IQR:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5IQR = Q3 − .
6The IQR of 3,5,7,9,11,13,15 is .
7Find the five-number summary of 3, 5, 7, 9, 11, 13, 15.
8Find the IQR for that dataset.
9Find the lower and upper outlier bounds for that dataset.
🚀 Section C · Challenge ● CHALLENGE 5
10Find the IQR if Q1 = 50 and Q3 = 75.
