EX-07-53 — Moving Averages with AVERAGE Function in Excel
In this video, we focus on creating and analyzing moving averages using the AVERAGE function—one of the most accessible yet powerful tools in Excel data analysis. Whether you’re tracking performance over time, reviewing trends, or comparing fluctuations, moving averages smooth out short-term volatility to help identify underlying patterns. This example uses a dataset of monthly traffic totals from a regional airport, showing actual monthly values alongside 3-month and 6-month moving average calculations. By applying the AVERAGE function across rolling intervals, we demonstrate how to calculate these smoothed series manually—without needing any built-in forecasting tools or add-ins. The results are compiled into a side-by-side table, making it easy to compare the raw data against both moving averages. Then we bring it all to life with a dual chart comparison, visually illustrating how trend lines stabilize as the averaging period increases. For those learning what is data analysis, this lesson highlights how to filter out noise and focus on long-term movement. It also shows how basic functions can be layered to produce insights usually reserved for more advanced platforms. This segment reinforces the practical role of Excel data analysis tools that already exist in every installation of Excel—no plug-ins, no setup, just built-in functionality and smart structure. Business users using Excel for data analysis will benefit from learning how to adapt this technique to sales tracking, budget reviews, or seasonality trends, with graphs that translate into clean executive visuals. More importantly, the breakdown helps demystify the AVERAGE function’s flexibility in data modeling. Whether you’re managing marketing metrics or tracking KPIs over time, learning how to build your own moving averages in Excel adds a deeper level of control and customization to reporting. This is another great example of how Microsoft Excel data analysis supports both technical accuracy and visual clarity in real business workflows.
