What are thresholds in data analysis?

Thresholds in data analysis are predefined limits that help determine when a certain action should be taken or when data should be flagged for further investigation.

Can you give me an example of how thresholds are used?

Sure! For instance, in quality control, a threshold might be set for the maximum allowable defect rate in a batch of products. If the defect rate exceeds this threshold, the batch is rejected.

How do I determine the right threshold for my data?

Determining the right threshold often involves statistical analysis, historical data review, and understanding the context of your data. You may also consider using techniques like control charts.

What happens if I set the threshold too high or too low?

If the threshold is set too high, you might miss important signals or anomalies. Conversely, if it's too low, you may end up with too many false positives, leading to unnecessary actions.
