6. Anomalous Data
Sometimes you make a data set and one number looks really weird
This is anomalous data
Anomalous data is useful – it can tell you if your equipment isn’t working right, or maybe you forgot to control for a variable
If your averages and percent error are strange, look for anomalous data
Graphs can help you spot anomalous data!
