At a physics lab, the voltage of a spinning dynamo is measured 10 times, results: 12.20, 12.10, 12.13, 12.20, 12.11, 11.98, 12.19, 12.09, 12.05 y 12.24.
What's the median of the voltages?
a-Me=11.98
b-Me=12.11
c-Me=12.12
d-Me=12.13
Thanks

http://www.wolframalpha.com/input/?i=sort+%7B12.20%2C+12.10%2C+12.13%2C+12.20%2C+12.11%2C+11.98%2C+12.19%2C+12.09%2C+12.05%2C+12.24%7D the middle of the stack is between 12.11 and 12.13 the average or midpoint of those is 12.12 i believe
