An error log is a simple table where you record the mistakes you made while handling or analyzing data so you can learn from them. It helps you avoid repeating the same errors in the future.

Steps to Make an Error Log

Create a Table with columns like:
- Step/Task: What you were doing (e.g., tallying, calculating mean).
- Error Made: Describe the mistake (e.g., counted the same number twice).
- Correct Method: Write how it should have been done.
- Lesson Learned: Note what you will do next time to avoid it.
Fill It Immediately after spotting a mistake, so you don’t forget what went wrong.
Review Regularly before starting new data-handling problems to remind yourself of past mistakes.

Example Error Log Table

Step/Task	Error Made	Correct Method	Lesson Learned
Tally Marks	Counted one number twice	Re-check tally after each group	Double-check after completing 5 tallies
Finding Mean	Forgot to divide by total items	Add all values ÷ total number of items	Write formula before solving
Drawing Graph	Used unequal intervals	Choose equal, continuous intervals	Decide interval width first

An error log is like your personal improvement tracker. It helps you become more accurate in calculations and improves your confidence in data handling.
