About this Gig
Are your business decisions backed by data or just gut feeling? I'll run rigorous statistical tests on your data so you know exactly what's working, what's not, and why.
Whether you're testing two versions of a landing page, comparing sales across regions, or analyzing survey results, I'll deliver clean, interpretable results with proper methodology.
What I can analyze:
- A/B and multivariate testing (conversion rate, revenue impact, click-through)
- Hypothesis testing: t-test, Mann-Whitney U, Chi-square, ANOVA, Kruskal-Wallis
- Correlation and regression analysis
- Descriptive statistics and distribution analysis
- Effect size calculation and statistical power analysis
What you'll receive:
- Full analysis in Python (Jupyter Notebook)
- Clear interpretation of results in plain English
- Visualizations: distribution plots, confidence intervals, boxplots
- PDF summary report with conclusions and recommendations
To get started, I'll need:
- Your dataset in CSV or Excel format
- A description of what you tested and what question you want answered
- Your preferred significance level (default: α = 0.05)
Not included: data collection or scraping, dashboard or BI tools, real-time monitoring setup.

FAQ
What kind of data do I need to provide?
A CSV or Excel file with your raw data — for example, two groups of users with their respective conversion outcomes, sales figures, or survey scores. The more complete and clean the data, the better the results.
What if my data is messy or has missing values?
Basic data cleaning is included. If the dataset requires significant preprocessing work, I'll let you know upfront before starting.
Which statistical test will you use?
It depends on your data type and research question. I'll select the most appropriate test — for example, t-test for comparing two group means, Chi-square for categorical data, or ANOVA for multiple groups — and explain why in the report.
Will I understand the results even if I'm not a statistician?
Yes. Every report includes a plain-English interpretation of the findings alongside the technical output. You'll know exactly what the numbers mean and what action to take.
What if the result shows no significant difference?
That's still a valid result — and an honest one. I'll deliver the full analysis regardless of outcome, including what the findings mean for your business decision.
