So far, black population of a state has allowed me to pick the primary winner 93.3% of the time

Text cross-posted from GDP:
States already predicted will be folded into the model itself after next Tuesday for May contests, so some of the later states may change after next week.
Hypothesis: Simply by analyzing the percentage of a state's population that is black, I believe you can fairly accurately predict the "winner" of a state in upcoming primaries and caucuses. There will be misses, I am sure, but I'm bored, so let's see how this works out. I'll bump the thread and fill in actual results (With insightful commentary like, "Boy, that one was wrong!"
as primaries go on...assuming people are interested in my validation or humiliation, as the case may be.
So let's begin with states that have already voted
Your key for numbers below:
State Rank for Black Pop. State % of Pop. that is Black
All numbers from 2010 Census
Bernie Wins
44 NH 1.22%
33 CO 4.28%
31 MN 4.57%
26 OK 7.96%
49 VT 0.87%
29 KS 6.15%
32 NE 4.50%
47 ME 1.03%
16 MI 14.24%
48 ID 0.95%
43 UT 1.27%
Avg Black Pop 4.28%
At +1 Standard Deviation 8.38%
Hillary Wins
40 IA 2.68%
23 NV 9.00%
5 SC 28.48%
6 AL 26.38%
12 AR 15.76%
3 GA 31.4%
25 MA 8.1%
10 TN 16.78%
18 TX 11.91%
9 VA 19.91%
2 LA 32.4%
1 MS 37.30%
11 FL 15.91%
14 IL 14.88%
19 MO 11.49%
7 NC 21.60%
17 OH 12.04%
35 AZ 4.16%
Avg Black Pop 17.79%
At -1 Standard Deviation 7.80%
Prediction Methodology: If a state's black population is less than Bernie's 1 St Dev number, I predict he wins. If it is more than Hillary's 1 St Dev number, I predict she wins.
So my straight up, no commentary predictions (Note: this isn't a prediction of margin of victory, just who comes out on top as the state's winner. I also do not include territories):
34 AK 4.27% Bernie Correct
38 HI 3.08% Bernie Correct
36 WA 3.74% Bernie Correct
30 WI 6.07% Bernie Correct
42 WY 1.29% Bernie Correct
13 NY 15.18% Hillary Correct
21 CT 10.34% Hillary Correct
8 DE 20.95% Hillary Correct
4 MD 30.1% Hillary Correct
20 PA 10.79% Hillary Correct
27 RI 7.5% Bernie Correct
22 IN 9.07% Hillary Sanders--Clinton won black vote by 52%
37 WV 3.58% Bernie Correct
24 KY 8.2% Hillary Correct
41 OR 2.01% Bernie Correct
28 CA 6.67% Bernie
50 MT 0.67% Bernie
15 NJ 14.46% Hillary
39 NM 2.97% Bernie
46 ND 1.08% Bernie
45 SD 1.14% Bernie
** DC 50.7% Hillary
Now there will be some misses here, because the two data sets overlap in the 2nd Standard Deviation (Mean+2*StDev vs Mean -2*StDev), so the question will become which states and in which direction. That said, misses should favor Hillary as her Standard Deviation is over twice as wide as Bernie's (Wider standard deviation means more variation in the numbers. In this case, wider Deviation means Clinton has been more successful among a wider variation in black population than Bernie).

OP - thank you again for contributing this OP> This is why I like hosting this group - we get real gems that we can read through without a lot of noise!
I still think CA is going for SOS Clinton. I just do.
