A histogram is a visual interpretation of numerical data showing the number of data points falling within a specified range of values. Authors can add a prompt, set the grid coordinates, set frequency axis, bin axis, and add static bars. Students can add responses by clicking on a bar and moving it. This is a machine scored interaction.
