(2) to help plan experiments (if you know you need 3 sig figs to do a calculation, you might use a graduated cylinder instead of a pipette, or a pan balance instead of an analytical balance). Instead of thinking of sig figs as the enemy, you should think of it as a SIMPLE method of estimation precision.
