Challenge Problems
Push your limits with advanced challenges
A researcher collected data from 150 households in a community of 1200. 30 households did not respond. Calculate the expansion factor and discuss how this information can impact urban transportation planning.
💡 Hint: Be thorough in applying the formula!
You are tasked with adjusting survey data due to an underestimation of survey responses. If your initial calculated expansion took into account 15% non-responses, but further analysis shows this should actually be 25%, recalculate the factor and discuss potential outcomes.
