Central Tendency & Variability
Practice I
• Alexa and her housemate, Maya, are interested
in finding out whether they are better off driving
or busing to work (they both work in the same
office). In an effort to answer their question,
Alexa drove to work and Maya rode the bus for
10 consecutive days. They each timed their trips
to the office and recorded the times. The results
(in minutes) are listed below:
