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 mean is the one to use with symmetrically distributed data; otherwise, use the median. If you follow this rule, you will get a more accurate reflection of an 'average' value. This question was at the heart of a UK news story in 2005, where the use of median or mean was at the bottom of substantial national confusion. The following paragraphs tell the story. In early April 2005 there was considerable debate in the UK media about whether 'average' incomes had gone up or down.
