Range:
Standard Deviation: 30.79
For women’s race from 2015 World Championships:
Mean: 1917.92
Median: 1913.01
Range:
Standard Deviation: 14.64
The technology used: Calculator and Microsoft Excel
2. If the timing in the men’s race failed to activate at the start of the race and instead
began to record the times x second into the race then all the competitor’s time would
be affected. To find their true times, x seconds should be added to each of the
competitor’s recorded times. The median calculated in question #1 would be affected
too because the median is the middle number in a sorted list of numbers. Since all of
the data would change if the timing failed to activate, the median would also change.
