We define your question together, and I turn the data into a clear answer. We start with a sample. You have data, but your question doesn’t fit any ready-made report type — something specific to your business, like “which product group sells more in which region, and how does that relate to season.” This page is about **custom data analysis** questions that don’t fit a pattern: we clarify the question together, and I turn your data into a clear answer. If your question fits one of the patterns below, that page is a faster and cheaper path: - Want to **forecast future sales**? → [Sales Forecasting](https://oguzerol.com/en/sales-forecasting/) - Want to **segment your customers**? → [Customer Segmentation](https://oguzerol.com/en/customer-segmentation/) - Want to know **who’s leaving and why**? → [Customer Churn Analysis](https://oguzerol.com/en/customer-churn-analysis/) - Want to see **which products sell together**? → [Basket and Cross-Sell Analysis](https://oguzerol.com/en/basket-and-cross-sell-analysis/) - Just want **messy data cleaned up**? → [Excel Data Cleaning](https://oguzerol.com/en/excel-data-cleaning/) ## How It Works 1. **The question gets clarified.** “Analyze my data” is too broad a request; something concrete like “which product group drops in which month” gets a much faster and more accurate result. That clarification itself is part of the job. 2. **A sample gets tried first.** A small sample of your data gets run through first — you see whether the approach works, and we don’t enter a large job on an abstract promise. 3. **The analysis gets scaled up.** Once the sample is approved, the full dataset gets worked on. 4. **The result gets presented clearly.** Not a pile of raw numbers — a summary that says “these three findings show this,” in a format you can act on. ## Who This Makes Sense For Any business whose data question doesn’t fit a ready-made pattern, but who has data at the Excel/Sheets level. This is the situation I run into most with small and mid-sized businesses without a data team — the question exists, the data exists, nobody’s building the bridge between them. ## The Mistake I See Most Often **Diving into the data before the question is clear.** An analysis that starts with “find something in this data” usually ends up with irrelevant or shallow findings. Without a clear question first, the result turns into charts that look impressive but don’t actually help you decide anything. ## What It Does Not Do - **It doesn’t make investment or strategic decisions.** I present the finding; you make the call. - **It doesn’t magically fix bad or incomplete data.** If data quality is poor, I say so upfront — sometimes the first job is cleaning it. - **It doesn’t profile individuals.** The analysis works on aggregate/anonymized data; I don’t build a setup that targets individuals. ## You Can Hire Me for This **You can hire me for this:** remote, billed hourly. Timeline depends on the complexity of the question and data volume; I give you a realistic estimate after the sample run. To start, just share your question and a sample of your data. Write to me from the [contact page](https://oguzerol.com/en/contact/). ## Frequently Asked Questions ### My data is very messy — does it need cleaning first? Usually yes, but that’s treated as a separate step — I look at a sample first and tell you how much cleaning is needed. Sometimes cleaning takes longer than the analysis itself. ### How much data do I need? Depends on the question, but the general rule is: little data doesn’t produce a reliable result. You can’t look for a year-long pattern in a few weeks of data — we assess this together during the sample review. ### Do I need a tool beyond Excel? Most analyses finish at the Excel/Google Sheets level. If data volume is large or the analysis needs to repeat regularly, I can suggest a more automated setup. ### How do I receive the result? I deliver a report summarizing the findings along with the supporting data behind it — not just a chart, but an explanation that answers “why is this happening.” [Back to top ↑](https://oguzerol.com/en/ai-data-analysis/#icerik) ## You may also find these useful [Customer Churn Analysis | Who Left, and Why?Find the common traits of customers who left, flag at-risk customers, and get a retention plan built around what the data shows.
