About Repeatability
- If a scientist cannot get the same results when repeating an experiment then the experiment is considered unreliable.
- If an experiment cannot be repeated then it is likely that there were control variables that were not properly controlled.
- Reliable conclusions cannot be drawn from an experiment which is not repeatable.
