Fathom Overview
Workshop on using Fathom in School Improvement Planning (SIP)
What is it?
Fathom is a software program that you can use to explore your SIP data– Produces tables, graphs, statistics,...– Exposes relationships that exist within the
data
How is it used?
You can import data into Fathom from Excel and other programs
“Drag and drop” icons onto the page to easily create graphs and tables
How is it used?...
Allows you to explore data relationships– look at the same data in different ways– “highlight” data of interest in many graphs
at once
The Fathom Document
Dynamic Statistics
Fathom documents contain objects that represent various ways of looking at data.
The objects in the document are dynamically linked to one another.– If one object changes, the others are
automatically updated This makes Fathom an ideal environment
for exploring data.
Fathom Documents
Fathom documentscontain text, data, tables, graphs, andother objects thatdisplay and analyzedata.
Fathom documentsare created byadding objectsto the Fathom Window.

The Menu Bar and Shelf
The Menu bar provides access to actions that you may wish to carry out.
The Shelf provides access to objects that you may wish to add to your Fathom document.

Importing Data
Adding a Data Collection
To add a Collection to your Fathom document, drag a Collection off the Shelf
The Collection is currently empty
Using Spreadsheet Data
To copy data from a spreadsheet
1. Open the spreadsheet.
2. Select all cells that contain data and column headings (CNTRL-A).
3. Copy (CNTRL-C) the cells.
Using Spreadsheet Data
Go to your Fathom document
Select the empty Collection in your document
Paste (EditPaste Cases or CTRL-V) the data into the collection
Cases in Fathom
The individual “rows” of data in the spreadsheet are now “cases” in Fathom.
After pasting in data or importing, the Collection is now populated.

Viewing Data
Inspecting Collections
Double clicking on a Collection launches the Inspector
The Inspector allows you to view and edit the data and add new attributes
Double click to inspect
Attributes and Values
Attributes represent what types of data are shown in each case.– Each case has a value for each attribute– Generated data may have a formula.
attributes values
case number
Inspecting Cases
Dragging open a Collection will show each case as an individual icon.
Double click on a case to inspect it.
Drag corner to see full collection
Double click to inspect
Adding Tables
You can view your data like in a spreadsheet by using a Table object
1. Select the Collection
2. Drag a Table object off the Shelf and onto the document

Entering Data
Using the Inspector
You can add data to a Collection using the Inspector
Double click on the Collection to open an Inspector
Clicking on <new> lets you create new data attributes
Adding New Cases
To add new cases you can either: 1. Select the Collection, and choose the
menu item DataNew Cases
2. Right click on the Inspector and choose New Cases from the context menu
edit values
navigate cases
Editing in the Inspector
You can add new values for cases by typing them into the Inspector
Use the arrow buttons at the bottom of the Inspector to move between cases
Using Tables
Cases can also be added and edited using a Table
Select the Collection and drag a Table off the Shelf
Click on the cells to edit the values
Click on <new> to add new attributes
Graphing Data
Creating an Empty Graph
To create a newGraph, simply drag a Graph object off theshelf and dropit into the document
Adding Data with Inspectors
Open an inspector on the Collection
Drag the attributes that you want to graph onto the axis
If only one attribute is dragged “count” is placed automatically onto the other axis
Adding Data with Tables
Create a Table for the Collection Drag the columns that you want to
graph onto the axis
Changing the Graph Type
When one attribute is plotted, the default graph is a “dot plot”
The graph type can be changed by clicking in the top right corner
Exploring Data
Different Views of Data
Objects in Fathom are dynamically linked
Selecting a Case in one object will highlight it in all other related objects
Selecting data
A selected group in one graph will be highlighted in all graphs
Click onone barto see thesame groupin other graphs
Summarizing Data
Summary tables give a a good overview of key statistics (mean, standard deviation, etc.)– Drag a summary table off
the shelf– Drag attributes onto
the arrows to be displayed either as rows or columns
