What you’ll learn
Describe a distribution in context.
Key idea
Use minute units and preserve the observation scope; similar sample sizes need not imply matching summaries.
Center and spread are separate sample summaries; equal sample sizes do not imply equal summaries, and sample summaries do not guarantee every school student's value.
Worked example
Enter the exact value or ordered values in the format requested below.
Eight observed reading times are (2, 10, 18, 26, 34, 42, 50, 58) minutes. Use median-of-halves; enter median,IQR as two comma-separated exact numbers.
- Eight observations give median=(26+34)/2=30; half medians give IQR=32.
- The measured range is 2-58 minutes; statements describe these samples, not every school student.
Answer: 30,32
