Hello mfb, the problem as I see it .. Is one correct to define the results as 1 Standard Deviation above the mean or 2. This is my concern. Thank you for your interest. Your advice will be very much appreciated. Charlie

Dear WWGB. "So , Charlie! , you're not clear on what distribution to use ?" I think is the very politest way one could describe my current frustration :confused:! Thank you for your continued interest in my difficulty. The answer I am sure is obvious to many , but remains elusive to me...

Thank you mfb, that is my humble but critical point.

hello, and thanks to everyone I am a she by the way not a he. :oops:, and by the look of things not the brightest at the moment. "However, if the results of the coin toss are given by a Net Gain/ Loss value i.e. wins - losses. So after player A makes 1000 predictions the net score = +32. Would...

Understand, So then the net score of +32, in 1000 tosses is actually 1 Standard Deviation ? Hope I'm right this time, and thanks for your help.

?? The net score , correct predictions - incorrect predictions by the player after 1000 predictions is + 32. i.e. the player made 32 more correct predictions than incorrect predictions.

When tossing a fair coin 1000 times a player correctly predicts 532 outcomes. Then I think I am right in saying that result is about + 2 Standard Deviations from the mean. sqr root 1000 x .5 x .5 = 15.81. 32/15.81= 2.02.However, if the results of the coin toss are given by a Net Gain/ Loss...
