Statistics: discrete qualitative variables, graphs

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

I am attaching my two options and each option has 2 variable.

a. Select Two Variables: From one of the Discussion Board Data Sets in Doc Sharing, select two variables. The first variable will be both discrete and qualitative. The second variable will be both continuous and quantitative. Be sure to indicate the name of the dataset you are using and the names of the variables. Note which variable is discrete and which is continuous and how you can tell. Be sure to include the definitions for discrete and continuous variables as well as qualitative and quantitative variables as part of your response.

b. Create Two Graphs: Using the two variables you have selected, create an appropriate graph for each variable to show or describe each variable. You will create two separate graphs, one for the discrete variable and one for the continuous variable. (Hint: do not put both variables in the same graph) Attach both fully labeled graphs to your post using the Add/Remove option. For each of your graphs, be sure to include all titles, labels, and information needed to correctly interpret your graphs. For example, if appropriate, include a label along the vertical y-axis and a label along the horizontal x-axis.

c. Explain and Discuss your Graphs: For each graph, explain why the particular graph you selected is appropriate for the data described by the graph. What particular elements of the graph do you want the reader to notice? What is the overall impression that you expect the reader to have from looking at the graph?

(a)

A discrete variable is one that cannot take on all possible values in the range. For instance, if you ask participants to give you a rating on a 7-point Likert scale. Only seven responses are possible for this variable, 1, 2, 3, 4 5, 6 and 7.

A continuous variable has an infinite number of points between two amounts, such as with the weight of something. You can always have an amount in between two different amounts.

Qualitative variables are characterizing the item, or categorizing using judgment or similarity or some classification scheme. You can sort into colors, for instance. ...

Solution Summary

Your discussion is 373 words and a reference and two graphs in Excel, one bar chart and one scatter diagram for penny type and weights.
