Answer 2

wait..what is a margin of error?
can you please explain?

Answer 3

also, can you please explain your answer of why it's 45% through 51%...
firstly, i don't really understand this... and the margin of error. |o|

Answer 4

A margin of error is basically that ± sign. The 48% might be wrong within 3%, so just add or subtract them and you get a range of numbers where the right percentage might be.

Answer 5

ohhh get it now. so the margin of error is like basically you add 3, since it's 3%, to the 48, and you get 51% and then you subtract 3% from 48 also, and then you get the range?
so that's how the margin of error is? thanks so much!

Answer 6

You're welcome. :) Oh, and the ± sign is usually called "plus or minus."

Answer 7

oh. thanks. by the way, how do you make the PLUS OR MINUS SIGN? :)

If you have a Mac, alt shift plus. If not, idk. :P
