    Getting central value in a list

    Hi In a list, how do I get the center value in a fast way? I've got a sensor, but sometimes it sends incorrect values. What I am thinking is to try 5 measures and take the central value. It's enough for me. For example, if I get : 78, 84, 83, 0, 85, the central value is 83 (0-78-83-84-85) Let...
