pdf Interquartile Range - Quiz

This multiple-choice quiz assesses students’ ability to calculate the interquartile range (IQR) across a variety of real-world data sets. Students analyze numerical data involving animal speeds, quiz scores, contest results, fish weights, gasoline prices, and other contextual scenarios. For each problem, students must correctly determine Q1 and Q3 and compute the IQR.

The quiz includes data sets with both even and odd numbers of values, requiring students to consistently apply quartile procedures. Decimal values, percentages, and monetary amounts are incorporated throughout, strengthening precision and reinforcing the connection between statistical measures and authentic contexts.
