I can help with:
Data cleaning (missing values, duplicates, formatting, coding)
Descriptive statistics (means, SD, medians, percentages)
Pre vs post comparisons (paired t-test / Wilcoxon, effect sizes)
Survey / quiz scoring + item analysis (% correct, difficulty, improvement)
Visualizations (bar charts, trend charts, before/after plots)
Dashboards (Excel / Power BI) and automated reporting
Academic or business reports (tables formatted for thesis / publication style)
Deliverables are always clean, labeled, and export-ready.
