    Hi all

    Hoping ye can give a mathamatical dunce some advice. I am trying to put together an archery anaylsis excel sheet to let me know how my shooting is improving/going crap. The way archery scoring works is that the target is made up of 10 concentric circles, with the inner circle worth 10 points and each circle worth one point less as you move out to the outer circle. One round of shooting consists of 30 shots.

    Could ye tell me what stat function would be the best indication of accuracy (closest to the center of the target) and precision (how close the shots are to each other) in each round? Could ye also give me the excel syntax for the functions as well?

    All the best.

    for accuracy you wont be able to tell just by which circle you're in - you need to specify direction as well (e.g. "inner circle at 3 o'clock")

    for precision as well you need to specify the direction as well

    to be honest i would just draw out the circles on an a4 sheet, photocopy it, measure the precision and accuracy on that using a ruler, and then note them into a spreadsheet. you could implement the functions but it would be messy and involve coordinat geometry (basically you would have to overlay some grid on your target)
