TIP
ОглавлениеUse common sense to report final values according to the correct rules of rounding – don’t just report what the computer tells you. This principle – using your common sense to interpret computer output – will come up again and again throughout this book.
TABLE 1.3 Impact of Rounding Styles on Mean Value
| Original Value | Correctly Rounded to Nearest Even Digit | Incorrectly Rounded (Always Upward) |
| 163.5 | 164 | 164 |
| 164.5 | 164 | 165 |
| 165.5 | 166 | 166 |
| 166.5 | 166 | 167 |
| Average = 165 | Average = 165 | Average = 165.5 (rounded = 166) |
