The online Survey provides a source of quantitative data that can be graphed, analyzed, or downloaded for use off-line. Since the online data set is constantly being updated, you should download the database for activities requiring all students to work with the same data. Once downloaded, the database can be easily loaded into any standard spreadsheet as a comma-delimited file.

• What percentage of the respondents indicated that family will be more important when they are old? How can this percentage be converted to a fraction or ratio?
• Using the online survey graphing program, construct a graph of the responses to the assertion "Most of the Elderly I know are proud of their age." What are the parts of this graph (ie. axes, legend)? Ask students to estimate the actual number of responses based on their reading of the graph.
• Calculate the mean, median and mode of a data set. Discuss which is the most accurate measure of the "average" of a data set. Use graphs for illustration. Have the class take the online survey. How do the results compare to those of the whole database? What is the difference between a sample and a population?
• Calculate the standard deviation. Discuss what it means in the real world. What is the purpose of finding this number?
• What is the probability that a student living with at least one grandparent strongly agrees with the statement that the elderly are proud of their age (you may select any two responses to use for comparison)? Are the answers to these questions independent or dependent events? What are some real-world explanations for the relationship between these two responses?
