What is 75 to the nearest tenth?

Answer 1

I assume the question concerns rounding to tens (rather than tenth). If tenth, nothing need be done.

Some people argue that 5 should always be rounded up. I disagree for the following reason:

In statistics such a procedure would introduce an upward bias (rounding down every time would introduce a downward bias). To avoid that, you need to round 5 up half the times and down half the times. Rather than rely on generating random numbers, and make it difficult for anyone else to see what was done, some people (including myself) round 5 to an even number.

So 75, rounded, would be 80.
