## Calculating Standard Deviation

The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs.

You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. Percent Error Formula If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine.
