    I would read the file line by line, parse the strings and convert the desired ones from a string to a double and then compute the ar. mean.

    Alternatively you can simply copypaste it and compute it in a notepad without any use of programming

    Are you sure the values in the third items are negative?

    Do you have any thoughts on how you can accomplish this? Come up with a general "big-picture" idea first, then start refining it into steps until you come up with the necessary pseudo-code. If you get stuck along the way, tell us where and how you're stuck and we can offer more specific advice.

    Some words to consider: "read", "store", "count".
