Chi Squared Test/Reliability Factor
Joel -
Here's a simple straightforward application from the Rad Health Handbook
(RHH 1984):
1. n >= 10 observations (our in-house minimum)
2. c >= 10000 counts (single count theoretical sd <= 1%)
3. Calc n average
4. Calc experimental sd for n-1 df (RHH 1984, p. 47)
5. Calc theoretical sd = sqrt of n average
6. Reliability Factor = (exp sd)/(th sd) (RHH 1984, p.48)
7. Plot results on graph from RHH 1984 p.185
8. Follow instructions, apply professional judgment
Let me know if you need more info.
