Some people advise you to round up 0.5. Others say round down. The problem with either approach is as follows:
In the first case
If the number is 0.0 you don't need to round
If the number is 0.1, 0.2, 0.3 or 0.4 you round down
If the number is 0.5, 0.6, 0.7, 0.8 or 0.9 you round up
So 4 downs and 5 ups (and one no change).
Net Result: you introduce an upward bias.
In the second scenario, you introduce a downward bias through rounding.
Possible solution:
Round up from 0.5 half the time, round down the other half. That satisfies the bias problem but introduces another - that of reproducibility. If someone else were to look at your data would they round up/down the same way you did? Unlikely. You need a system which will round 0.5 up half the time and down half the time but where the decision is made for you.
Hence the best solution is the answer given above: Round up or down so that the new last digit is even.
11.25 is already two decimal places.
To round 1.55 to two decimal places, you need to look at the third decimal place, which is 5 in this case. Since 5 is equal to or greater than 5, you round up the second decimal place by adding 1 to it. Therefore, 1.55 rounded to two decimal places is 1.56.
rounded to two decimal places after the decimal point: 6.73
