Most Stable Longshot Tracks over Past 12 Months

[Rick]

Put up a new longshots chart yesterday.

While I was doing it I looked at the figures to see which tracks seems to produce longshots at a steady and good pace. I tried some STDEV and other stats and they all point to:

SUN
HOU
LS

They all have a STDEV less than 2.5 and are all above 70 on my rating.

Now the trick is trying to figure out what works at each track.

Good hunting.

ok Rick...I'm not smart...what is STDEV? :D

Standard Deviation.

A low standard deviation means that the numbers were fairly consistent over the 12 month period. For the most part it was like a high of 84 and low of 78; or close to it.

If you need a more detailed explaination, I can look it up. In fact I just did. Here it is from Excel:

STDEV
See Also

Estimates standard deviation based on a sample. The standard deviation is a measure of how
widely values are dispersed from the average value (the mean).

Syntax

STDEV(number1,number2,...)

Number1, number2, ... are 1 to 30 number arguments corresponding to a sample of a
population. You can also use a single array or a reference to an array instead of arguments
separated by commas.

Remarks

STDEV assumes that its arguments are a sample of the population. If your data represents
the entire population, then compute the standard deviation using STDEVP.

The standard deviation is calculated using the "nonbiased" or "n-1" method.

Logical values such as TRUE and FALSE and text are ignored. If logical values and text must
not be ignored, use the STDEVA worksheet function.

Example

Suppose 10 tools stamped from the same machine during a production run are collected as a
random sample and measured for breaking strength.

The example may be easier to understand if you copy it to a blank worksheet.

How?

Create a blank workbook or worksheet.

Select the example in the Help topic. Do not select the row or column headers.


Selecting an example from Help

Press CTRL+C.
In the worksheet, select cell A1, and press CTRL+V.
To switch between viewing the results and viewing the formulas that return the results, press
CTRL+` (grave accent), or on the Tools menu, point to Formula Auditing, and then click
Formula Auditing Mode.

A
1 Strength
2 1345
3 1301
4 1368
5 1322
6 1310
7 1370
8 1318
9 1350
10 1303
11 1299

Formula Description (Result)
=STDEV(A2:A11) Standard deviation of breaking strength (27.46391572)

All that didn't copy well. If you have Excel just click on help and look up STDEV.

Hurrikane, aren't you sorry you asked? I sure am. :)

2/3 are Texas tracks and SUN is in New Mexico I think. Just shows you what first 1st time Tequila or Jalapeno On or Jalapeno Off can do to these fine creatures...

Glen has found the answer to the success in the Asmussen and Norman barns!

Bruce...yes I am. :D
