As for the median value, there's a relatively easy way to do this in PHP:

I think Erik has gotten his terms mixed. He wants the "most-chosen" value, which is the "mode" and not "median". To get the mode, use array_count_values();

I told you guys I was bad at math! I don't even remember the terms... thanks to everyone who replied to this thread with advice, it looks like I can do: - grab all values from the desired inputs and slap them into an array - run the array against array_count_values() to get the number of each input value in that array (in the form of a new array) - rsort the resulting new array (of 'value => occurrences' form) to put the highest-numbered array at the beginning of the array - the key of the first element in this rsorted array is the value I am looking for -- the most-chosen value from the initial user inputs - array_flip the array inside the first element of the rsorted array to make the key into the value and vice versa - my desired value is now the value of the first element in the array It seems like a lot of work, but sounds logical. The end result is the most-chosen value from the user inputs becomes the value of the first element in the array returned by array_count_values() after that array has been rsorted and flipped. Crazy!
