Introduction to Statistics

Day 6 12th March

Today we were shown the statistics of our 3.4 km run. For this we were to round our times to the nearest minute and then to tell them to one of the Wambana staff. We then got a statistic of how many people got which time and found that the most people on a single time was three with us having the same times at 15 and 24 minutes. We then grouped these together to create a graph. We found that we had a right biased positive distribution. This means that we have more people with faster times then slower times. This would remain the same but it shows that we have a fairly steady and good group of poeple for running and that we have a distance of about only four minutes between each of our groups. We conducted a graph of stats which looked like this:

Wardli 2 Wardli 3 Wardli 4 Wardli 5
min 16 14 13 13
max 24 25 24 30
range 8 11 11 17
mode n/a 25 24 n/a
median 23 18 16 18
mean 21 19.40 18.40 21
Q1 16 14.5 14 14
Q3 24 25 24 29.5
IQR 8 10.5 10 15.5

The IQR is the average distance between our times. This shows that Wardli two was the most constant group while Wardli five was the most diverse.
