The video tutorial covers the basics of graphing data, focusing on bar graphs and histograms. It explains the differences between these two types of graphs, with bar graphs representing categorical data and histograms representing quantitative data. The tutorial provides step-by-step instructions on how to create and interpret both types of graphs, using examples to illustrate the concepts.
