Graphing and Data Analysis Techniques

This video tutorial demonstrates how to use Microsoft Excel to plot two linear data sets on the same graph for comparison. It covers selecting data, inserting scatter plots, adjusting axes, editing data series, adding a second data set, formatting the graph, and adding trend lines with equations. The tutorial concludes with finalizing the graph and providing title suggestions.
