Fathom Overview Workshop on using Fathom in School Improvement Planning (SIP)
What is it? n 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? n You can import data into Fathom from Excel and other programs n “Drag and drop” icons onto the page to easily create graphs and tables
How is it used?... n 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 n Fathom documents contain objects that represent various ways of looking at data. n The objects in the document are dynamically linked to one another. –If one object changes, the others are automatically updated n This makes Fathom an ideal environment for exploring data.
Fathom Documents n Fathom documents contain text, data, tables, graphs, and other objects that display and analyze data. n Fathom documents are created by adding objects to the Fathom Window.
The Fathom Window the Menu bar the Shelf the Fathom document
The Menu Bar and Shelf n The Menu bar provides access to actions that you may wish to carry out. n The Shelf provides access to objects that you may wish to add to your Fathom document. the Menu bar the Shelf
Importing Data
Adding a Data Collection n To add a Collection to your Fathom document, drag a Collection off the Shelf n The Collection is currently empty
Using Spreadsheet Data n 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 n Go to your Fathom document n Select the empty Collection in your document n Paste (Edit Paste Cases or CTRL-V) the data into the collection
Cases in Fathom n The individual “rows” of data in the spreadsheet are now “cases” in Fathom. n After pasting in data or importing, the Collection is now populated. Empty CollectionPopulated Collection Data Import
Viewing Data
Inspecting Collections n Double clicking on a Collection launches the Inspector n The Inspector allows you to view and edit the data and add new attributes Double click to inspect
Attributes and Values n 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. attributesvalues case number
Inspecting Cases n Dragging open a Collection will show each case as an individual icon. n Double click on a case to inspect it. Drag corner to see full collection Double click to inspect
Adding Tables n 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 Table
Using Tables case click to add new attribute n Use Tables to view, edit, or create new cases and attributes n Tables provide a “spreadsheet” style view of the data collection name case numbers attributes
Entering Data
Using the Inspector n You can add data to a Collection using the Inspector n Double click on the Collection to open an Inspector n Clicking on lets you create new data attributes
Adding New Cases n To add new cases you can either: 1. Select the Collection, and choose the menu item Data New Cases 2. Right click on the Inspector and choose New Cases from the context menu
edit values navigate cases Editing in the Inspector n You can add new values for cases by typing them into the Inspector n Use the arrow buttons at the bottom of the Inspector to move between cases
Using Tables n Cases can also be added and edited using a Table n Select the Collection and drag a Table off the Shelf n Click on the cells to edit the values n Click on to add new attributes
Graphing Data
Creating an Empty Graph n To create a new Graph, simply drag a Graph object off the shelf and drop it into the document
Adding Data with Inspectors n Open an inspector on the Collection n Drag the attributes that you want to graph onto the axis n If only one attribute is dragged “count” is placed automatically onto the other axis
Adding Data with Tables n Create a Table for the Collection n Drag the columns that you want to graph onto the axis
Changing the Graph Type n When one attribute is plotted, the default graph is a “dot plot” n The graph type can be changed by clicking in the top right corner
Exploring Data
Different Views of Data n Objects in Fathom are dynamically linked n Selecting a Case in one object will highlight it in all other related objects
Selecting data n A selected group in one graph will be highlighted in all graphs Click on one bar to see the same group in other graphs
Summarizing Data n 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
