What is "bad data", and how is it worse than no data?
- mp05 3y agoData gathered from a poorly designed study? I don't think it needs explaining why making decisions on nonsense is just that.
- tsimionescu 3y agoThink of things like "lines of code written" or "bugs closed" as measurements of productivity or quality. These are real things that people have used in real published studies - and any conclusion drawn from them is obviously bogus.
- itishappy 3y agoMeasurement noise, other experimental errors, small sample size, cherry picking. It's worse than no data because you can draw incorrect conclusions. Have a really dumb example: All of the developers I work with are short, therefore all developers must be short, and we could save time by filtering job applicants by height. (Note: I work with only one developer. He's great!)
