Box Plots
Grade 6 · Math · Statistics and Data · Hawaii, USA
Lesson Summary
A box plot displays data using the minimum, first quartile, median, third quartile, and maximum.
Explanation
A box plot, also called a box-and-whisker plot, divides data into four equal parts. The box shows the middle 50% of the data, with a line at the median. The whiskers extend to the minimum and maximum values. The left edge of the box is the first quartile (Q1), and the right edge is the third quartile (Q3). Box plots make it easy to see the spread and center of data, compare data sets side by side, and spot outliers.
Practice Questions
Q1: In a box plot, what does the line inside the box represent?
Answer: The median of the data set.
Q2: A box plot shows Q1 = 20 and Q3 = 40. What is the interquartile range (IQR)?
Answer: 20 (Q3 minus Q1: 40 - 20).
Q3: If a box plot's whiskers are very long, what does that tell you about the data?
Answer: The data is widely spread out, with values far from the center.
