Reproducibility and Standard Deviation
Both accuracy and precision are desired for proper data analysis. They are not mutually exclusive. This is heavily dependent on the person and the measurement tool as well. You must have heard of the idiom "A bad workman quarrels with his tools"... this is true in science as well. Even if you have million dollar instrument, and the operator is unskilled, the data will be garbage. The premise that it is easier to make mistakes is not valid and generally RSD of 1-5 % is routine in scientific measurements. An RSD of 20% would be considered too high.
