How do I calculate the average of a set of moneylines?

[JohnGalt2341]

Let's say I've made 10 MLB Moneyline bets over the last few days. The lines were as follows:
1. -118
2. +148
3. +122
4. -166
5. -143
6. +105
7. +142
8. -120
9. +115
10. +137

If I wanted to know what the average of these lines were how would I figure it out? Any help is appreciated.

Convert to decimal, add them all up, divide by 10. Convert back to American.

Who is John Galt?

Has anyone heard of this guy?

Rappaport?

TTo's right on.

Just assign a regular number to each ML value and move up and down accordingly based on the numerical value and the (+/-) sign.
Then just add them up and average it out till you get a number you can then convert back to an original betting value fro ML.

ie: (-110) = 0
(-111) = 1
(-112) = 2
(-113) = 3....etc

And do the opposite for DOG values (+100) = 0, (+101) = 1, (+102) = 2
(+110) = 10....etc

This is the only way I could think of as well but I thought there might be an easier way. So with the 10 Lines that I posted I came up with an average line of +102.4. That doesn't seem right.

Can you not just add them up and divide by the count?

Not 100% sure on the .4 part, but just doing some quick math, 102 is correct.

[Chi_archie]

yeah 102.2

[tto827]

yeah 102.2

That's what I got.

For future reference, another way to do it, just forget the 100 base, and deal with -118 as -18, or +105 as 5. Add them up that way, then divide by 10, you get 2.2, add that back to your 100 base, and boom, 102.2, a little easier then doing the conversions twice.

Obviously, if you get a negative, don't subtract it, but if you get -5, then that is -105.

there is an easier way. just add them up using only the part that is more or less than 100. -18+48+22 etc. then divide by 10. you get 2.2.
add that to your baseline of 100.


beat me to it.

[Chi_archie]

Yep I did it the same as the two above

[Chi_archie]

now stink tank this shit

I think this is the easiest way. Thanks.
