For this next bit you need a calculator...

Add together the best times* of all six dogs and divide by 6 to obtain the average time. Plot the average time and draw a broken line (-----) across all six dog graphs.

This is a good visual check about the assumption that: ‘the winning time of the race will, at least, be the average time’. That is not always the case but it is an advantage to have some sort of graphical guide for selection purposes.

By viewing the finished graph, you would expect that: ‘any dog selected would have the ability, or could improve, to reach the average time’. The top dogs would, of course, have that ability.

If you concluded that a dog did not have the ability because it was very old, or too young, for example, then you would not select it; thus improving the odds of selecting the winner.

That’s all for now…

Come racing!!
