=Lesson= TSW...
 * 1) Open web browser.
 * 2) Go to [], click on the Handling Data link.
 * 3) Click on the play button beside the activity named, "[|Mode, Median and Mean]"
 * 4) Work through the first set of Median, Mode, and Mean as a group.
 * ===Group Set of Data - Median activity===
 * Drag and drop buildings into the order of least to greatest.
 * Drag the red and white "**Median**" sign to the building that is physically in the **middle** of the ordered list.
 * ===Group Set of Data - Mode activity[[image:MMM-Mode.jpg align="center"]]===
 * Drag and drop the buildings to the tally chart to create tally marks.
 * Drag the red and white "**Mode**" sign to the bottom of the tally box with the **most** number of tally marks.
 * ===Group Set of Data - Mean activity[[image:MMM-Mean.png align="center"]]===
 * On a sheet of paper, add all of the building heights to find the sum.
 * Using either the paper or a calculator program in the computer, to divide the sum of the heights by the number of heights to find the mean.
 * In the Macs, there is a calculator program in the Dashboard.
 * 1) Click on the Dashboard icon.[[image:MMM-DashboardIcon.png width="90" height="89" align="center"]]
 * 2) Click on the buttons of the calculator that shows in the Dashboard that pops up.[[image:Dashboard-Calculator.png align="center"]]
 * 3) Click in the empty space outside of the calculator to return to the activity.


 * The students work through a few sets independently as teacher monitors and corrects misconceptions of median, mode, and mean.**

Extend the Lesson with Real World Data
To bring in relevancy, students will find and use numbers for items in their life. (An example - Google Shopping for a new video game. The numbers are the prices. This data could be used for several different things. For this example, we will search with Google's shopping search to find the prices of Guitar Hero, then narrow the search. The "Sort by" drop-down can be used to reorder the numbers from lowest to highest.


 * 1) Open a web browser.
 * 2) Type www.google.com in the address box and hit RETURN key.
 * 3) Click on the "Shopping" link at the top of the window.
 * 4) Type the item, in this case "Guitar Hero 5", into the search engine and click SEARCH.
 * 5) Refine the search by adding search terms such as "Wii" to add specifics or "**-**Band" to remove terms.
 * 6) Use the prices as the data.
 * 7) Open OpenOffice.org Spreadsheet program. (Microsoft Office Excel or any other spreadsheet program may be substituted if OpenOffice.org is not already installed to the student machines.)
 * 8) Copy prices from the Google Shopping Search into individual cells to form a list.
 * 9) Reorder them as lowest to highest.
 * 10) Identify the median as the number in the ordered list. Type the word "Median" in the cell beside the number that is in the middle. If it is a list with an even-numbered amount, the median is halfway between the to most middle numbers in the list.
 * 11) Identify the mode by typing the word "Mode" in the cell beside the number that appears the most in the list.
 * 12) Add the numbers, then divide the sum by the number of items in the list to find the mean.
 * 13) Type the word "Mean" in a cell and type the average below the label.
 * 14) Type their name in another cell.
 * 15) Print their spreadsheet.
