Box Plots & Interquartile Range — Easy Worksheet 2
Grade 6 · Whoobee Name: ____________________ Date: __________
Use the box plot or the data to answer each question.
How to solve
Order the data and find the median (the middle). Q1 is the median of the lower half and Q3 is the median of the upper half (leave the median out of both halves when there is an odd number of values). IQR = Q3 - Q1 and range = greatest - least. On a box plot, the box runs from Q1 to Q3, the line inside is the median, and the whiskers reach the least and greatest values.
Example
What is the median?
Answer: 12
Not quite. The answer is
💡 The line inside the box marks the median. It is at 9, so the median is 9.
✓ Correct!
