4. Calculate the impact dimension D: Use the next method to calculate the impact dimension D:
D = (φ1 – φ2) / sqrt((φ1 * (1 – φ1) + φ2 * (1 – φ2)) / 2)
the place φ1 and φ2 are the chances of the 2 classes.

Suppose we wish to research the results of a brand new therapy on a binary variable (illness presence or absence). We’ve got 100 topics, and 60 are handled whereas 40 usually are not. We calculate the chances as 0.6 for the therapy group and 0.4 for the management group.
| Class | Frequency | Chance |
| — | — | — |
| Therapy | 60 | 0.6 |
| Management | 40 | 0.4 |
We are able to now calculate the impact dimension D utilizing the method:
D = (0.6 – 0.4) / sqrt((0.6 * (1 – 0.6) + 0.4 * (1 – 0.4)) / 2) ≈ 0.43
This means a reasonable impact dimension, suggesting that the therapy has a major affect on the binary variable.
