Nazia G.

Mathematician & Statistical Data Analyst who turns complex data into clear, reliable answers. 🏆 Among Top 10% Mathematics Expert & Analyst On Upwork, trusted by many clients worldwide. I've spent more time around numbers than most people are comfortable with, a Mathematics and Statistics background, years of lecturing, and now freelance work where I don't get to hide behind theory. When a client hands me a dataset, my first question is never 'what model should I run,' it's 'what decision does this actually need to answer.' The method comes after that, not before. 📌 What I Do I help researchers, businesses, and organizations turn complex datasets into clear statistical results, meaningful insights, and evidence-based conclusions. That means I can help with hypothesis testing, regression analysis, ANOVA, survey analysis, research replication, statistical modeling, predictive modeling, and forecasting. From research and survey data to large business datasets, I work on projects that require more than simply running statistical software. Whether you need to validate research findings, analyse survey data, test hypotheses, identify relationships in your data, or build a predictive model, I select the appropriate method based on your research question or business objective, then validate and interpret the results so they are clear and meaningful. 💡 Why Clients Work With Me ✔️ 6+ years of experience in statistical analysis, quantitative research, mathematics, and data analysis. ✔️ 100% Job Success Score on Upwork, with completed projects involving large-dataset analysis, research replication, SQL analysis, R-based analysis, sustainability data, and statistical modeling. ✔️ Real-world experience with US-based companies, including Align Education, LLC for large-dataset statistical analysis and Tomco USA for predictive modeling on a Wealth Decision Engine. ✔️ Experience across both research and business problems, adapting the analysis to the data and the question instead of using a standard template. ✔️ I focus on interpretation as much as calculation, so you get results you can understand, explain, and use 📊 My Core Services: Statistical Analysis • Hypothesis Testing • Regression Analysis • ANOVA • Descriptive & Inferential Statistics • Correlation & Statistical Testing Research & Quantitative Analysis • Research Data Analysis • Quantitative Research • Research Replication • Survey Data Analysis • Sampling & Research Methodology Predictive & Data Analysis • Predictive Modeling • Time-Series Analysis & Forecasting • Exploratory Data Analysis • Data Cleaning & Validation • Data Visualization 🛠 Tools I Work With Python | R | SPSS | SQL | Excel | Stata I use Python and R for statistical analysis, modeling, data cleaning, and visualization, SPSS for research and survey analysis, and SQL/Excel when the project requires database analysis or structured data work. 🎯 My Approach The goal is not to make analysis complicated. The goal is to make the right conclusion easier to see. Whether you need help analyzing a dataset, validating research results, testing a hypothesis, analyzing survey data, building a regression model, or developing a predictive model, I focus on selecting the right approach for your specific objective.
