anor277 answered · 1 month ago 1 Answer What is precision? Calculate the percent error for your experimental density of water.? A percent error calculation simply tells you the magnitude of the mistakes that took place during the experiment. It is possible to have accurate measurements that are imprecise if the deviation between the measurements is small but the measurements differ significantly from the accepted value.
