Take a larger sample so that the likelihood that an event that large  occurring by chance is lessened. Simple random error will more closely  approximate zero.  The following figure illustrates the effect of increasing the signal (bear) to  noise (wind) ratio by decreasing the magnitude of the noise (wind). Very  few samples of ten consecutive chance noises get very loud (divide all the  scores in noise distribution by some value). What this does geometrically is

Unformatted text preview: to squeeze in the noise distribution. Decrease Magnitude of Noise As you have seen statistical decisions are based on an explicit acceptance of the trade-off between better detectability (decreasing misses) and better reliability (decreasing false alarms). In statistics we had decided to minimize misses consistent with no more than 5 false alarm errors per 100. We accepted some errors of one type in order to attenuate errors of the other type....
