Make a graph or chart of the data. Histograms, scatter graphs and box plots can all be used to display descriptive statistics. Make handouts for each student, or prepare a chart before class on the whiteboard.
Prepare a list of the raw data that was used to make the graph or chart. For example, if you use a histogram for your class, you may also want to prepare a frequency distribution table showing the raw data used to prepare the chart.
Describe the graph or chart and the raw data to your students. Verbal explanations of descriptive statistics are a vital component of understanding. To ensure your students are listening, ask them to participate in a classroom discussion about the data and invite questions.
Incorporate written material into your lecture. Written material usually comes in the form of a textbook but if you don't have a textbook, prepare handouts or instruct students to take notes in class.
