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.
One problem with using the mean, is that it often does not depict the typical outcome. If there is one outcome that is very far from the rest of the data, then the mean will be strongly affected by this outcome. Such an outcome is called and outlier. An alternative measure is the median. The median is the middle score. If we have an even number of events we take the average of the two middles.
