Good work Karen.

The percentages are somewhat misleading - actually insignificant since the sample sizes are too small particularly at 14.1, 14, and 16.1. The confidence intervals are just to large.

The normal way to deal with that is to combine "like categories." If 14 and 14.1 are combined with 14.3 that gies 23 horse in that category. If 16 and 16.1 are combined with 15.3 that gives 35 inthat category.

The percentages now become:

<14.3  23 starts 10 finish  43.5%
14.3    23 starts 14 finish   60.9%
15       64 starts  27 finish  42.2%
15.1    39 starts  24 finish  61.5%
15.2    33 starts  17 finish  51.5%
>15.2  35 starts  19 finish   54.3%

So in ranking order of the categories

15.1
14.3
>15.2
15.2
<14.3
15

Given the numbers are I would suggest that the probability of finishing the Tevis is pretty much independent of height.

I didn't get the height on all of the horses this year, but looks like I had 216 of them, from the entry information provided on the Tevis site.  Here they are sorted, showing height and how many -- these were from the start list.

16.1     2
16      10
15.3   23
15.2   33
15.1   39
15      64
14.3   23
14.2   16
14.1     3
14       4

And this sort is from the finishers list

16.1   1
16      4
15.3   14
15.2   17
15.1   24
15      27
14.3   14
14.2     6
14.1     2
14        2

To make it a little interesting, here are the finishers sorted by % of finishers divided by # of starters in each height:

14.1   67
15.1   62
15.3   61
14.3   61
15.2   52
16.1   50
14 0.  50
15 0.  42
16 0.  40
14.2   38
