TL;DR
AI is useful for summarizing patterns in data you provide directly and suggesting what to investigate further. It should not be trusted to calculate exact figures without independent verification, especially for anything decision-critical.
Paste the actual data, do not describe it
Giving AI the real data directly, rather than a vague description of it, produces far more accurate and useful analysis.
Ask for patterns, not just numbers
Prompting for what stands out or what is worth investigating tends to surface more useful insight than asking only for raw calculations.
Verify any specific number independently
For anything used in a real decision, recalculate key figures manually or with a formula tool rather than trusting an AI-stated number outright.
Use follow-up prompts to go deeper
Asking a clarifying follow-up on an interesting pattern, rather than a single broad prompt, usually produces better analysis, echoing the prompt engineering guide.
Frequently asked questions
Can I trust AI to do exact calculations on my data?
Not reliably for anything important; independently verifying key numbers is worth the extra step.
What is AI best used for in data analysis?
Spotting patterns worth a closer look and summarizing findings in plain language tends to be where it adds the most value.
