For
example; I say I am 6 feet tall. Is this correct? |
||||||||||||
Sure,
to one sig fig! But, I am really not being honest. I am really 5'7''. |
||||||||||||
This too, is not exactly correct, if I measure my height with a tape measure, I can get as close as 5'6.75''! You see, I am exaggerating my height because I feel small! | ||||||||||||
Sig. figs. are important. They tell us what the best measurement is at any certain time.You can't arbitrarily use as many sig. figs as you want! | ||||||||||||
