Number of Siblings and skewed data
The number of siblings for 3 statisitics classes.
Make a histogram for the number of siblings. How is this skewed? Is the data discrete or continuous?  smcdaniel04  Apr 3, 2015  21KB  1410  Responses to Math 1530K Fall 2013 Survey  smcdaniel04  Aug 30, 2013  2KB  213  Intro Survey  smcdaniel04  Sep 18, 2012  3KB  195

What's your major?
Construct a pie chart and bar chart for students majors in the Spring 2012 intro stats class.  smcdaniel04  Jan 25, 2012  293B  749 
Students heights
Create a histogram for students’ heights. May need to experiment with different bin widths (e.g 3, 5). Comment on the shape of the distribution.  smcdaniel04  Jan 23, 2012  239B  1000 
Intro Stats GPA
Grade point average for 24 students in intro stats class.
Create a histogram for GPA (If not using StatCrunch, you may want to create a frequency distribution first.) Note: May need to try different bin widths (e.g. 0.5, 1). Is the data continuous or discrete? Comment on the shape of the distribution.  smcdaniel04  Jan 23, 2012  178B  1715  Political Breakdown Grouped by Gender

2. Construct a relative frequency distribution for students’ classification.
3. What percentage of students are Freshmen?

Cigarette Consumption vs CHD Mortality
Now that cigarette smoking has been clearly tied to lung cancer, researchers are focusing on possible links to other diseases. The data below show annual rates of cigarette consumption and deaths from coronary heart disease for several nations. Some public health officials are urging that the US adopt a national goal of cutting cigarette consumption in half over the next decade.
Examine these data and write a report. In your report you should:
1. Include appropriate graphs (e.g. scatterplot, residual plot) and statistics (e.g. mean and SD);
2. Describe the association between cigarette smoking and coronary heart disease;
3. Create a linear model;
4. Evaluate the strength and appropriateness of your model;
5. Interpret the slope and yintercept of the line;
6. Use your model to estimate the potential benefits of reaching the national goal proposed for the US. That is, based on your linear model, if the US were to cut its cigarette consumption in half (from 3900 to 1950), what does the linear model predict would happen to the CHD rate.
7. You should use Statcrunch to generate nice looking graphs and output as needed. Be sure to size them appropriately. No need for a 8x10 scatterplot; Make your graphs about 3x3. You should scale them in Statcrunch first, then copy and paste into Word.

The following data represents the foreign language being studied based on a simple random sample of 30 students learning a foreign language.

Causes of Fatal Accidents by Decade (percentage)
An investigation compiled information about recent nonmilitary plane crashed. The table below is compiled from the http://planecrashinfo.com/ accident database and represents 1,300 fatal accidents involving commercial aircraft, worldwide, from 1950 through 2009 for which a specific cause is known. Aircraft with 10 or less people aboard, military aircraft, private aircraft and helicopters are not included. Create a pie chart and bar chart for the data for the total “All” column.  smcdaniel04  Sep 6, 2011  264B  853  Class Breakdown by Classification

Height Data set
The height of 50 students is given. One can create a histogram and see the bimodal nature of the data. There is an interesting article that argues against human height being bimodal: http://faculty.washington.edu/tamre/IsHumanHeightBimodal.pdf
