In this experiment, we'll ask you questions about patterns of data in a graph. The graph will only stay on the screen for 15 seconds before disappearing, so pay close attention! After the graph disappears, we'll ask you to type a description of TWO interesting comparisons or patterns that you noticed in the data - so try your best to remember at least TWO!

Graph background: Imagine that you are looking at how two kids, Charlie and River, grow over time. Their heights are measured at ages 8, 10, and 12.

For now, only the axes are visible. When you are ready, you can reveal the data (for only 15 seconds) by pressing the right arrow key on your keyboard.

You must answer the following questions before completing the experiment.

Did you notice anything that didn't make sense in the plot? (If not, simply write "no" in the box below; if yes, please describe)

You must answer the following yes or no questions before completing the experiment.

Did you previously notice that River's height gets lower between ages 10 and 12 (i.e., River shrinks during those years), which seems unlikely?

Please answer honestly! This may (or may not) be a trick question, so it is very important to us that you answer it based on what you really saw.

Yes     No

You must answer the following yes or no questions before completing the experiment.

Did you previously notice that Charlie's height stays the same between ages 10 and 12 (i.e., Charlie does not grow during those years), which seems unlikely?
