 * = = Is there a Relationship? = ||
 * 1. || ===Work with the people in your group to measure the following for each person.===

All measurementsshould be in centimeters.
||
 * 2. || ===Put each measurement into the indicated lists on the second page.===
 * ===length of armspan (fingertip to fingertip,arms outstretched) into **List 1[[image:person.png align="right"]]**===
 * ===your height into **List 2**===
 * ===the length of your thumb into **List3**===
 * ===the length of your ear into **List 4**===
 * ===the distance from the top of your head to your belly button into **List 5**===
 * ===the distance from your belly button to your feet into **List 6**=== ||
 * 3. || ===Once everyone has completed their measurements, all the information will becollected and added to your list.===

Whenyou have all this information, use your calculator to find averages (**mean**) for each list.
||
 * 4. || ===The lists will be used to create several different graphs called **“scatter plots”.**===

**Graph** **4**: thumb versus height
||
 * 5. || ===For **each** graph:===

c) If there is a relationship, explain it in words or with an algebraic equation if you can.

 * 7. || ===**__Drawing ascatter plot__****:**===

eg **Graph1**: **armspan** versus **height** (**List1 v List 2**)
> ===Your teacher/mentor will show you how to do this.===
 * ===If you have access to a computer,select one of the graphs to be drawn and transfer your data to the computer program.===
 * ===To draw it by hand on graph paper:===
 * 1) ===Check the range of measurements **ie**from smallest to largest in each list.===
 * 2) ===Each axis of your scatter plotshould **start with zero**, so decide ascale to fit the largest measurement in.===
 * 3) ===Label the bottom axis (theHORIZONTAL one) as **armspan** and labelusing the scale you chose.===
 * 4) ===Repeat this with the VERTICAL axislabelled as **height.**===
 * 5) ===Enter your points. The points should **NOT** be joined up!===
 * 6) ===Put a label (**name**) at the top of your graph.===
 * 7) ===Your teacher will show you how todraw a “line of best fit” through some of the points.=== ||
