Creating a Survey and Analyzing and Displaying the Data Results from a Survey

This curriculum unit is intended to infuse more statistics into an Algebra One class. However, it may be used in other math classes.   Students are expected to pick a topic, create a survey, make it accessible on-line for people to participate, and analyze the resulting data.  They will be expected to enter their data on a spreadsheet and display them using several different types of graphs.  Charts, frequency tables, scatter plot, and stem-and-leaf plots will be examined during this unit.  They will learn how to calculate the appropriate sample size for the confidence level they desire; and how to calculate central tendencies and determine which measure of central tendency is the best reflection of the data.
