Question about Texas Instruments TI-86 Calculator
I am trying to calculate standard deviations with this calculator -which means I need it to display an exact answer. I keep getting 1.007 when the answer should be 1.0068. I have tried changing the mode settings around and still I can't get it to come up with the right answers. I need to complete my lab experiment yesterday, can anyone help me??!!
If you're sure the answer isn't really 1.007, check to see if the calculator is in fixed mode. You can change it to scientific notation(that'll give you lots of digits past the decimal place, or I prefer engineering, which is scientific except all powers of ten are in multiples of three).
