This method is perhaps the most useful for demonstrating the effectiveness of social distancing and other public health measures for " flattening the curve ". Besid Representing cumulative frequency data on a graph is the most efficient way to understand the data and derive results. Line graph 2. This allows areas of lower contrast to gain a higher contrast. One can draw these graphs either separately or combined. The limiting points of each class are called the lower class limit and the upper class limit, and the class width is the distance between the lower (or higher) limits of successive classes.
