I am trying to compute median household income in various zipcodes based on buying habits. While implementing the dataflow, I am now stuck in the Map, where I cannot find a median() function. Any ideas?
You can compute the median easily using the following modeling algorithm:
Another way you can find the median is by doing a Profile on the household income column (provided that you have converted the column to its correct datatype, that is, integer or float).
Alternatively, you can simply sort the table by the column, and jump to the middle row.
