Cumulative Frequency Curve. A plot of the cumulative frequency against the upper class boundary with the points joined by line segments. Any continuous cumulative frequency curve, including a cumulative frequency polygon, is called an ogive. There are two ways of constructing an ogive or cumulative frequency curve. The curve is usually of shape.

Dec 29, 2008 · Yep, keep your cumulative frequency graph and say things like the range of boys is higher than girls. Draw lines from the 25%, 75% to get the middle 50% and then say the spread of boys or the girls is greater. Say hat the quartiles are in comparison to each other. Whats median, mean, mode, etc...

Box plots, a.k.a. box-and-whiskers plots, are an excellent way to visualize differences among groups. They manage to carry a lot of statistical details — medians, ranges, outliers — without looking intimidating. But box plots are not always intuitive to read. How do you compare two box plots?

Notice also that the numbers along the x axis are evenly spaced, while along the y-axis, we have powers of 10 evenly spaced. Finally, here's the graph of `y=5^x` on lin-log (linear vertical axis, logarithmic horizontal axis). of commodities are published (Graph A4). Over the past 20 years, roll returns on the GSCI have on average been negative, which has offset cumulative price increases of around 200 per cent and resulted in a net excess return over this period of close to zero. While many commodity price indices use weights

The graph below shows a frequency distribution on the left, and a cumulative distribution of the same data on the right, both plotting the number of values in each bin. The main advantage of cumulative distributions is that you don't need to decide on a bin width. Instead, you can tabulate the exact cumulative distribution as shown below.
