teststyle = median
If there are groupby columns, they comprise the UPI. Otherwise, ChiSq is the UPI.
| Column | Data Type | Description |
|---|---|---|
| Chisq | Float | Chi-Squared statistic. |
| DF | INTEGER | Degrees of freedom. |
| MedianPValue | Float | Probability associated with Chi-Squared statistic. |
| MedianPText | Char | Text description if probability is outside table range. |
| MedianCallP_0.01 | Char | Chi-Squared result:
|
Example
The following table shows how the Median test was computed on income over marital_status by years_with_bank. Results are sorted by years_with_bank. The tests show that values came from populations with the same median where MedianCallP_0.01 = a and from populations with different medians where MedianCallP_0.01 = p.
