Excel and data Analytics experience required

please understand the concept before accepting my bid

I’m looking for someone with a background in supply chain management, business analytics, or operations management who is proficient in using Excel for forecasting analysis. I need help completing an assignment that involves calculating forecast accuracy metrics — including Forecast Error, Forecast Percentage Error, Mean Percentage Error (MPE), and Mean Absolute Percentage Error (MAPE) — based on provided sales data for 1TB and 5TB hard drives over a two-year period. The work must be done using an Excel spreadsheet and include a written summary interpreting the results. Familiarity with forecasting methods and performance evaluation in business is a must.
