Statistics for Six SIGMA Green Belts with Minitab and Jmp

More precisely, the probability that a normal deviate lies in the range between − and + is 2010-03-22 Even if the experiment is conducted perfectly, there is no inference from 5-sigma to 99.99994 percent confidence. 5-sigma gives you the probability of getting certain data on the assumption that the null hypothesis is true (that it is just a statistical aberration), not the probability of the experimental hypothesis being true. The above mentioned "five sigma" criterion has been heavily publicized especially well when the Higgs boson discovery came together: it was clear from the start that a claim of observing the goddamn particle could only be put forth if one had data whose probability under the "no Higgs" hypothesis -the null- was below 0.000027%. 2016-07-13 5-sigma gives you the probability of getting certain data on the assumption that the null hypothesis is true (that it is just a statistical aberration), not the probability of the experimental hypothesis being true.

LIGO similarly compares a model of the observed noise to the observed noise plus the signal predicted by GR for black hole mergers. A five-sigma level translates to one chance in 3.5 million that a random fluctuation would yield the result. This level of certainty was required in order to assert that a particle consistent with the Higgs boson had been discovered in two independent experiments at CERN , [11] also leading to the declaration of the first observation of In most cases, a five-sigma result is considered the gold standard for significance, corresponding to about a one-in-a-million chance that the findings are just a result of random variations; six sigma translates to one chance in a half-billion that the result is a random fluke. The probability of occurrence over n=1,000 = 0.7% (millennials have a higher probability of having a heart attack (5-8%) than seeing a 5 sigma event). Or, it is like playing musical chairs at a The sigma (standard deviation) is multiplied with the numbers 1, 2, 3 etc to come up with a range. For example lets assume that the average of a data set is 10, while the sigma is 2. Hence 1 sigma will include all the data points between 10 +/-2 i.e.

A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects. Six Sigma strategies seek to improve the quality of the output of a process by identifying and removing the causes So what does five-sigma mean in relation to the discovery of the Higgs Boson? There are some nice explanations in the press.

For most purposes, this is a fine system. There are very few scenarios in daily life or most professions where 99.73% certainty or accuracy is … In short, five-sigma corresponds to a p-value, or probability, of 3x10-7, or about 1 in 3.5 million. This is not the probability that the Higgs boson does or doesn't exist; rather, it is the Five-sigma corresponds to a p-value, or probability, of 3×10 -7, or about 1 in 3.5 million. This is where you need to put your thinking caps on because 5-sigma doesn’t mean there’s a 1 in 3.5 The above mentioned "five sigma" criterion has been heavily publicized especially well when the Higgs boson discovery came together: it was clear from the start that a claim of observing the goddamn particle could only be put forth if one had data whose probability under the "no Higgs" hypothesis -the null- was below 0.000027%.
