The bottleneck mechanism occurs when the first stimulus is being processed, any other stimuli cannot be processed. The processing of the second stimulus is postponed which slows down reaction time. Neurons that take in information send this information to specific neural networks in different locations.
Sometimes the more telling statistic is the median, instead of the average â but in the age of average, it might take some effort to embrace the more accurate number.
The truncated mean uses more information from the distribution or sample than the median, but unless the underlying distribution is symmetric, the truncated mean of a sample is unlikely to produce an unbiased estimator for either the mean or the median.
