Do you round 0.5 up or down?

How do you round in statistics?
Summary tables must be rounded to no more than one decimal place.
Percentages appearing in reference and methodological tables must be rounded to no more than two decimal places except in certain methodological tables where finer breakdowns may be necessary..
How to do scientific rounding?
To round a number, first decide how many significant figures the number should have.
Once you know that, round to that many digits, starting from the left.
If the number immediately to the right of the last significant digit is less than 5, it is dropped and the value of the last significant digit remains the same..
What is the rounding method?
Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Example: 38 rounded to the nearest ten is 40. 1.
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down..

If the digits on the right-hand side are less than 5, consider them as equal to zero.
If the digits on the right-hand side are greater than or equal to 5, then add +1 to that digit and consider all other digits as zero..
What is the statistical convention for rounding?

- By convention, a fractional part of exactly 0.5 is rounded up.
We need a convention, because a number with fractional part 0.5 lies exactly between two whole numbers, so there is no 'closest' number to round to. - Put simply, if the last digit is less than 5, round the previous digit down.
However, if it's 5 or more than you should round the previous digit up.
So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up. - Rule: Either provide the exact fraction or decimal of the probability or round-off the final result to three significant digits.
Example: The probability of rolling a '4' with a single die is 1/6 or 0.16666666…, which would be rounded-off to 0.167.
