Box-and-whisker plot
Analyze Box-and-whisker plot in Grade 10 math: calculate measures of center and spread, interpret data sets, and apply Saxon Algebra 2 statistical methods.
Key Concepts
A way to organize data using five key values: the minimum, the first quartile (median of the lower half), the median, the third quartile (median of the upper half), and the maximum.
For the data {20, 22, 22, 28, 29, 31, 32, 32, 35}: Minimum=20, Maximum=35, Median (Q2)=29. First Quartile (Q1) is the median of {20, 22, 22, 28}, which is 22. Third Quartile (Q3) is the median of {31, 32, 32, 35}, which is 32.
Think of a box and whisker plot as a treasure map for your data! This plot gives you a visual five point summary. The 'box' shows where the middle 50% of your data lives, from the first to the third quartile. The 'whiskers' reach out to the lowest and highest values, showing the full range of your data's adventure.
