In a scientific context evidence is experimental or empirical data (although in some branches, well thought out mathematics may suffice). For example, in identifying a chemical compound, an analyst may present a spectrum to support their hypothesis but a reviewer may point out that it is insufficient, explain why by offering an alternative interpretation and state more data is needed, usually suggesting specific data that would be required. This sort of procedure happens constantly in the scientific method, repeating until everyone is happy that the data and explanation match.
