I have a T-84 plus.I trying to find the varience of these values, 1.51, 1.52, 1.54 , 1.36, 1.43 , 1.44, 1.61, 1.49. I put each value in the L list and calculated standard deviation but when I do the Sx box is alway empty.
I pressed stat then selected edit. There I inputed the data in the list. Then I pressed stat again went to the calculate window and pressed enter on 1-Var Stats. Then I press enter on calculated only to find Sx is empty. I tired to upload picture but the file size is too big.
