A sample of 286 gamma-ray bursts, detected by Swift satellite, is studied statistically by the {chi}{sup 2} test and the Student t-test, respectively. The short and long subgroups are well detected in the Swift data. But no intermediate subgroup is seen. The non-detection of this subgroup in the Swift database can be explained, once it is assumed that in the BATSE database the short and the intermediate subgroups form a common subclass.
