[12C] Percent of Total and Accumulating Statistic
HP12C Owner's Handbook gave example on how to use Percent of Total [%T]
I would like to extend it capability by using Accumulating Statistic [Σ+] so that by accumulating [Σ+] instead of Enter Add as show in the handbook and lost the Total Amount. By using the [Σ+] you retain the total by Recall Register 2 at any time and with this buildin statistic function this can also compute for the Average. Example: f [Σ] // Clear Statistic Registers 1. 1234 2. 2345 3. 3456 4. 4321 1234 [Σ+] > 1 2345 [Σ+] > 2 3456 [Σ+] > 3 4321 [Σ+] > 4 [RCL] 2 > 11356 // Total 1234 [%T] > 10.87 [CLx] 2345 [%T] > 20.65 // If forget to press [CLx] don't worry just Recall [RCL] 2 [CLx] 3456 [%T] > 30.43 // and try again. [CLx] 4321 [%T] > 38.05 g [Xbar] > 2839 // Mean g [S] > 1341.28 // Standard Deviation [RCL] 1 > 4 [√x] > 2 [÷] > 670.64 // Standard Error of the Mean Gamo
