pdf Creating Box And Whisker Plots From Decimal Data Sets

This worksheet provides structured practice creating box-and-whisker plots using decimal data sets. Students are given four different collections of decimal values and must first order the data, determine the five-number summary (minimum, Q1, median, Q3, maximum), and then construct an accurate box plot on the provided number line.

The data sets vary in scale and spread. Some focus on values between 0 and 2, while others extend to larger ranges such as 0 to 11. One problem includes very small decimal values between 0 and 0.22, requiring careful attention to place value and precision when identifying quartiles. Because students must move from raw decimal data to a graphical representation, the activity reinforces both computational accuracy and conceptual understanding of distribution.

By comparing multiple box plots, students begin to recognize how differences in quartiles, medians, and overall range affect the shape and spread of a distribution. This resource works well as guided practice, independent reinforcement, or formative assessment within a statistics and data analysis unit.
