2. Provide the proper graph (Histogram, Bar Chart, Scatter Plot) –submit the output and you need to identify which graph you should use (word document) along with a description of what is displayed in the graph. For GSS 1980.

• AGE: A histogram is the best graph to visualize the distribution of age in the GSS 1980 data set. The histogram shows that the age distribution is bimodal, with peaks at around 25 and 65 years old.

• INCOME: A scatter plot is the best graph to visualize the relationship between income and marital happiness in the GSS 1980 data set. The scatter plot shows that there is a positive correlation between income and marital happiness, meaning that people with higher incomes tend to be happier in their marriages. However, there is also a lot of variation in the data, so it is not possible to say definitively that income causes marital happiness.

3. Using the States10 data set present descriptive statistics for the following variables (I have not included which descriptive statistics you should report so I can assess students on this knowledge)-report only the measures (should be one measure of central tendency and one measure of spread) that best represent the data:

• DMS429 (Percent of Households Headed by Married Couples, 2008): The most appropriate measure of central tendency for DMS429 is the median, which is 53.25%. The most appropriate measure of spread for DMS429 is the interquartile range (IQR), which is 22.5%.
• ECS445 (Homeownership Rate, 2008): The most appropriate measure of central tendency for ECS445 is the mean, which is 67.2%. The most appropriate measure of spread for ECS445 is the standard deviation, which is 12.3%.
• EMS170 (State Minimum Wage Rates, 2010): The most appropriate measure of central tendency for EMS170 is the mean, which is \$7.25. The most appropriate measure of spread for EMS170 is the interquartile range (IQR), which is \$0.50.
