Moving Averages and Data Analysis

Dr. Grande's video tutorial explains how to graph a moving average in Microsoft Excel. It covers the setup of data, creation of line charts, and calculation of moving averages using Excel formulas. The video also compares different moving averages, such as 7-day and 28-day, to demonstrate their impact on data smoothing. The tutorial concludes with a summary and contact information for further assistance.
