Read the article "How to Display Data Badly," by Howard Wainer. It was published in the American Statistician in 1984, volume 38, pages 137-147. You can find it here:http://www.jstor.org/stable/2683253.
Next, scour the Internet (or if you are feeling particularly plucky, look through your company's annual report!) to find an example of a poorly made or misleading graph. Provide the graph and point out where the graph went awry.
Reproduce the data using a better (more illuminating, more honest, etc) graph format. You may have to do some guesswork on what the underlying data actually are.
1. Post an example of a poorly made graph. Provide the source of your graph.
2. Provide a brief discussion of what makes the graph a poor one. A couple of sentences.
3. Redo the graph (probably using Excel), making sure to correct the faults you identified in the original. Estimate data values to complete this last task.

Solution Summary

A guide to identifying a poorly made or misleading graph of statistics. A brief discussion for making the graph is provided.

Plot the graphs of the following and identify the graph that represents the cooresponding functions and justify your answer. Thank you!
1) y=2^x
2) y=log 2x (the 2 is subscript)
3) f(x)=6^x
4) f(x)=3^x-2
5) f(x)=(1/2)^x

A graph is outerplanar if it can be embedded in the plane so that every vertex lies on the boundary of the exterior region. Prove the following:
If G = G(p, q) is outerplanar with p >= 2, then q <= 2p - 3.

1) State the domain of the following:
2) The graph of is shifted to obtain each the following graphs. What is the equation of the function, g(x), for each graph? Write answers in terms of x2 and/or x.

Please draw these four graphs carefully as you would for a workplace memo. There are no equations or numbers in this exercise.
1.Demand increases; Supply increases. [Both curves move in the same direction.]
a.Demand increases more than Supply increases. (i.e. the D curve shifts more to the right than the Supply curve shi

Refer to the graph given below and identify the graph that represents the corresponding function. Justify your answer.
y = 4^x
y = log4x
Plot the graphs of the following functions. Scan the graphs and post them to the Facilitator along with your response.
1. f(x) = 5x
2. f(x) = 4x+2
3. f(x) = (1/3)x
4. f(x
