The Last Record:
- Look at the data carefully
- Do you have all the fields that you will need?
- Is it a number field? Is it text?
- Look for the patterns and trends
- Consider the source
- Are there controls in your data?
- Are you pulling from an outside source that may not always be available or updated?
- Identify the blind spots in your data
- Think about the questions you can answer using this data.
- Are there any limitations? If there are, you may need to supplement with additional data.
