Quality & evidence
Quality & evidence
ANSWER IN BRIEF
Separate demonstrated facts, provider claims and assumptions when comparing options.
Start with the right question
The evaluation entries explain sample evidence, quality checks and the basis of value indications. They support a comparison that shows uncertainty rather than concealing it inside a single numerical ranking.
Choose the next evidence step
Identify which claims can be checked now and which require a later buyer decision. Ask for enough evidence to choose the next step, not an unsupported promise of an outcome.

Comparing broker quality requirements — Compare Data Brokers
Compare quality requirements by the check, threshold, sample and intended use each candidate describes. General labels such as clean or premium are not a common measurement basis and should not be treated as evidence of equivalent acceptance standards.
Normalizing broker value indications — Compare Data Brokers
Normalize value indications by dataset scope, rights, cost basis and conditions before comparing them. Different numbers may describe different transactions, and an independent estimate should remain distinct from a broker’s expectation or buyer offer.
Comparing dataset qualification decisions — Compare Data Brokers
When brokers reach different qualification decisions, compare their intended buyers, review evidence and assumptions. A rejection for one use and interest for another may be consistent responses to different needs rather than contradictory judgments about the dataset itself.
