• Differentiate between categorical and numerical data• Consider other forms of data displays such as weather maps and dynamicelectronic information displays (e.g., a heart monitor) that use mathematicaldata to provide information quickly and in real time.Session 2 is devoted to basic displays of data (tally marks, pictographs, line plots, andbar graphs) that primary grade students can be expected to develop from their ownquestions and own experience. When interpreting these graphs, children will beintroduced to the idea that there may be a "shape" or pattern to the data beingdisplayed.Session 3 will address two types of graphs (scatter plot and line graph) that upperelementary and middle grade children can create when given a data set. Both scatterplots and line graphs need students to plot points on a coordinate plane as they did inthe Algebra unit. An informal introduction to "line of best" fit will ask pre-serviceteachers to notice and interpret a trend in a scatterplot.
