Document Summary
Netflix business problem: we need to do this, we need to do that all about loyalty. The number in the middle of an ordered sequence. May not take into account all data. It reduces affects that may be going on at either end of the scale doesn"t matter what happens, ex: Ex: easuring income, ordinary people and having bill gates he is outlier beyond most of the distribution, as most people are farther away. Middle person would be closer to the pen handler: adding an outlier in mean skews the data but for median: it does not mess. How to calculate median: first list all values in numerical order, find the middle value and that the median, odd number: easy middle, for even number: you take the middle numbers and divide them by 2. Which is the middle value: (9+1)/2 : 5 n+1 /2 gives u person who has median.
