 **Data About Us** __**Investigation 1:**__ Problem-Solving Goals:

 __**Investigation 2:**__ Problem-Solving Goals:
 * Describe data distributions
 * Use tables, line plots, and bar graphs to display data distribution
 * Recognize how the median, as a measure of center, responds to changes in the number and magnitude of data values.
 * Identify whether data are categorical or numerical.
 * Understand how mode, median, and range relate to numerical and categorical data.
 * Distinguish between and answer questions using vertical and horizontal bar graphs.


 * Group numerical data in equal intervals and display their distribution using a stem-and-leaf plot.
 * Compare two distributions displayed using back-to-back stem-and-leaf plots.
 * Identify outliers in a distribution.
 * Display distributors of paired data values on coordinate graphs.
 * Explore relationships between paired-data values whose distributions are displayed using coordinate graphs.
 * Explore intervals for scaling the vertical axis and the horizontal axis.

__**Investigation 3:**__ Problem-Solving Goals:


 * <span style="font-family: 'Comic Sans MS',cursive;">Understand the mean as a number that “evens out” or “balances” a distribution.
 * <span style="font-family: 'Comic Sans MS',cursive;">Create distributions with designated means.
 * <span style="font-family: 'Comic Sans MS',cursive;">Recognize the data with the same mean may have different distributions.
 * <span style="font-family: 'Comic Sans MS',cursive;">Reason with a model that clarifies the development of the algorithm for finding the mean.
 * <span style="font-family: 'Comic Sans MS',cursive;">Experiment with how the mean, as a measure of center, responds to changes in the number and magnitude of data values.
