| Definitionskos:definition | Standard deviation - true value known; significance level 50%. |
|---|---|
| has broaderbroader | 33 - linear error probable Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 50 %. |
| 55 - time accuracy at 50 % significance level Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 50 %. | |
| 69 - attribute value uncertainty at 50 % significance level Half length of the interval defined by an upper and a lower limit, in which the true value for the quantitative attribute lies with probability 50 %. | |
| 1D variable 50 % probability Confidence interval given by the probability P=50 % of the true value being between the lower and upper limit. | |
