Histogram and Data Interpretation

The video tutorial introduces histograms, explaining their definition and how they differ from bar graphs. It provides examples of when to use histograms versus bar graphs, focusing on numerical data grouped into ranges. The tutorial includes practice questions on interpreting histograms and selecting the correct histogram based on given data. It concludes with instructions for further practice on IXL.
