Accuracy and precision are two individual ideas. The common illustration distinguishing The 2 is to consider a target or bullseye. Arrows surrounding a bullseye suggest a high degree of accuracy; arrows extremely around to each other (potentially nowhere near the bullseye) indicate a significant degree of precision.
But In case the terminal zeros aren't significant if there is not any decimal level e.g., a hundred has only one significant determine.
