Well, isn't that a happy little question! When we round 50.5 to the nearest whole number, we look at the decimal part. Since 0.5 is right in the middle, we round up to the next whole number, which is 51. Keep on painting those numbers with joy!

To round 50.5 to the nearest whole number, we look at the decimal part (0.5). Since 0.5 is equal to or greater than 0.5, we round up the whole number part (50) by 1. Therefore, rounding 50.5 to the nearest whole number gives us 51.

Well, darling, if we're rounding 50.5 to the nearest whole number, we just need to look at that pesky little decimal. Since 0.5 is smack dab in the middle, we round up to the nearest whole number, which gives us a solid 51. Easy peasy lemon squeezy!

50.

Some, statistically naive people will say 51 but that is incorrect. 5 should always be rounded so that the preceding digit is even. If not, the rounding introduces an upward bias.

This is because you

  • do not round for 1 of the ten digits: 0
  • round down for 4 out ten digits: (1, 2, 3 and 4)
  • round up for 5 out of ten digits: (5, 6, 7, 8 and 9).

So you are rounding up more often than down. Hence bias.
