Compute and interpret mean, median, range, and interquartile range in context.
Interpret spread in context
Problem
Sprint times in seconds are \(12.4,~11.8,~12.1,~13.0,~11.9,~\text{and}~12.7\). Calculate the range and interpret what it measures.
Big Picture
What this problem is really about
For sprint times, the full spread runs from the fastest numerical time to the slowest numerical time. Identify the minimum and maximum, subtract the former from the latter, and retain seconds as the unit. Interpret that difference as the endpoint span of the performances, not as a typical time.
