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.
