    Some clubs still like to throw 50 target doubles events. What would be the average of a shooter who shoots the following scores in doubles: 92/100, 46/50, 94/100 and 47/50 ?

    I get 93 also. In order to make it equivalent you would have to put it in percentages. 92,92,94,94 divide by 4. 93

    I don't see how they could do it any other way, but it's possible.

    It's .93 but I think maybe Pat has a follow-up example that's a little bit different.

    93. Add targets broken (279), then divide by targets shot at (300).

    Sorry- Nobody has correctly calculated the average of the scores yet.

    OK.. I will take the bait.....The shooter has only shot three hundred targets, thus not at the 500 targets for an average. The shooter to will be defaulted unil the 500 targets are scored.

    OK. I'll bite.

    Maybe 93 on the hundred event and the 50 event is recorded separately as 46.5 or not at all. ???

    all the best,

    If this is his first 300 doubles targets shot, he would not have an average as of yet. But would be classed as AA because of his known ability. Or in any class at the discretion of the classifing committee.

    Pat, I'll bet Harold's right, his average (mean) is .93. His median is .93 following the convention of taking the score half-way between individual (N/2) and individual (N/2)+1 and his mode is .94 or .92.

    For classification purposes, the median, rounded if necessary to the nearest .01, is probably the best estimate of tomorrow's score but try teaching trapshooters how to get that!

    I certainly hope you aren't requiring .93 plus or minus .0116 or .01, since, while those two numbers would be needed to characterize the distribution (depending on your definition of SD, sample or population), they are _not_ required for the average, which is what you asked for.

    the average score is 69.75?!?? The average % used in classification would be 93.00%

    The average of 92, 46, 94, 47 is 69.75. An average is the sum of the x's over N (92+46+94+47 / 4).

    The proportion of targets broken is 93.

    The column on our card labeled average is only an average when we enter only 100 bird events. That column would be more correctly identified as mean % of targets broken. All of the above posters did indicate the correct number that should be entered on our mislabeled card.

    The number is 93. That is what I would have on my card if those scores belonged to me. If you can figure it out differently, please enlighten us. but take it easy with the heavy math as I only have a masters degree in engineering and do not have access to Matlab from home.

    balance365- I will, with pride, give you a once fired AA hull at the next shoot we both attend.

    HaveGunWillTravel - Do you really believe that 92+46+94+47 / 4 = 93?

    Drunk-Again - An "idiot servant"? I would not challenge the adjective but must question the noun.
