Fathom Activity 2

Create a Summary Table

Please Note:	This is a continuation of Activity 1. You will need to open your saved Fathom file (FathomAct1). You will be creating a summary table from the data provided for Group 1 and Group 2.

•	Click and drag a New Summary Table  into the screen.  Put it under the Collection 1 Table.
•	 Fathom puts an empty table in your document, as shown: 

•	Drag the Group attribute over the down-pointing arrow and drop it there.
•	Drag the Reaction attribute over the right pointing arrow and drop it there.
•	Make the summary table bigger as necessary, so you can see all information.
•	By default, Fathom will display count (the # of people in each group) and mean (the mean of each group).
•	We want to add other statistical information to this table. To add these, right click over the summary table and choose Add formula.
•	A new box will pop up: Create Summary Formula.
•	For each statistic, we want to use the attribute ReactionTime. Click on the Attributes tab and select ReactionTime. You will have to double click on this so it appears on the screen.  This is the first thing you will do for each formula.

•	We are going to start our summary table by inserting all the required information for a box and whisker plot (min, max, median, mean, Q1, Q3).
•	Open up the Functions tab (click on the + mark), scroll down to Statistical and open it up. Open the one attribute tab. Scroll down this list until you get to min. Double click on it. The window should look like this: 

•	Click OK and this new piece of information will show up in your summary table.
•	Repeat this process for: max, median, mean, Q1, and Q3. Each of these can be found under Statistical and one attribute. 
•	You will have to click OK on the Create Summary Formula box each time you add a new piece of information. 
•	After you have all the required information for a box and whisker plot, add the standard deviation (stdDev) in the same way.
•	Save this as FathomAct2.
