The "Two-Sample Test (Normal Approximation)" provides results with continuity correction, while the "One-Way Test (Chi-Square Approximation)" provides results without continuity correction.
The "(mean - mean 0) / standard deviation 0" output in the report is calculated using the continuous correction value as follows:
| (Rank sum - Expected rank sum + Sequential correction) / Standard deviation of rank sum |
Here, if "rank sum - expected value of rank sum > 0", the consecutive adjustment value is -0.5, and if "rank sum - expected value of rank sum < 0", the consecutive adjustment value is 0.5.
