Explanation

Scientific research is data driven, replicable and verifiable.

It grounds conclusions in systematically gathered empirical evidence.

Replication lets other researchers repeat a study and check results.

Verifiability means claims can be independently tested against evidence.

Being subjective is not a feature, since science aims at objectivity.

Personal bias is controlled through transparent, standardised procedures.
