I need two small CSV files—about 50 rows each—cleaned and analysed immediately after hire. The data come from a brief observational study, so accuracy matters. What I expect you to do within 1 ½ hours: • Clean both datasets and handle any obvious entry issues or missing values. • Build the requested pivot tables in Excel and arrange them in a workbook so I can inspect every step. • Run the required statistical tests directly in Excel and summarise the results next to each pivot. • Create clear, publication-quality charts (PNG) that match the pivots. • Package everything so the work is reproducible; if you use R or Python at any stage, include the script alongside the finished Excel workbook. When you send your bid, highlight similar analytical work you’ve completed so I can gauge your experience quickly. Speed and precision are essential—please be ready to start right away and deliver within the 90-minute window.
