Question

A data team at a nature preserve wants to draw conclusions about the presence and abundance of the bird species on the preserve. Their team’s naturalists collect this data, but for funding reasons the most recent data they have is from five years ago. Which aspect of good data are they missing?

Answer 1

They’re missing timeliness (currency) — the data are outdated. Five‑year‑old surveys may not reflect current presence or abundance, so conclusions could be invalid.
