About This Worksheet

This medium-level worksheet contains 14 problems designed for 6th Grade students practicing range and variability. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Measures of spread complement measures of center. Two data sets can have the same mean but very different spreads — understanding this distinction is essential for making valid comparisons and developing statistical literacy.

  • Calculate the range as the difference between maximum and minimum values
  • Find the first and third quartiles to calculate the interquartile range (IQR)
  • Use range and IQR to describe the spread and variability of a data set
  • Compare the variability of two data sets using their interquartile ranges
  • Identify potential outliers by comparing values to IQR-based boundaries
