Part 2: Descriptive Graphs using Statistical Software
Use data file that you created in Part 1 to answer the following questions. Copy all the charts generated from the statistical software into this WORD document and properly label each charts using Figure numbers (a point would be taken off if a chart or table has no number and label) as in the examples page shown in the later part of this assignment document. Please, for each of the chart you produced, write a sentence or two above of below the chart to comment on what you see from the chart.
1. Make a frequency distribution table for the gender variable to see the frequency distribution [in MS-Word, click on Insert and select Table].
[Use MS-Word to create a table for putting the frequency information here!]
2. Make a bar chart for gender variable.
[Copy and paste the graph here!]
[Write a sentence or two to comment on what you see in this chart.]
3. Make a histogram to display the distribution of the Height variable.
[Copy and paste the graph here!]
[Write a sentence or two to comment on what you see in this chart.]
4. Make a cluster bar chart (side-by-side bar chart) to examine the correlation between gender and Ate Fried Food variables.
[Copy and paste the graph here!]
[Write a sentence or two to comment on what you see in this chart.]
5. Make a scatter plot to examine the correlation between Weight and Height variables, and write a sentence to describe the trend you observed from the scatter plot. [Remove the one extreme value in Height data before making the scatter plot.]
[Copy and paste the graph here!]
[Write a sentence or two to comment on what you see in this chart.]
Note: (Practice Proper Labeling) Each chart or table in your assignment needs to have proper number and title. (See the following example.)
