Method of Instruction • This is an introductory session • Students will be exposed to a broad overview of the features and functions in Epi Info™ 7 • Hold questions until Question and Answer Sessions • Order of instruction for each module: • PowerPoint Presentation • Demonstration • Practice • End-of-Lesson Questions

  10. Module 1 – Introduction What is Epi Info™?

  11. What is Epi Info™? • A suite of free data management, analysis, and visualization tools designed specifically for the public health community. • Features include: • Rapid electronic form creation & data entry • Statistical analysis • Mapping & visualization • Used extensively throughout CDC, domestically and internationally.

  12. System Requirements • Generally, any Windows computer that has recently run Windows Update. • Specifically: • Windows XP, Windows Vista, Windows 7 • .NET Framework 3.5 • 256 MB of RAM

  13. Epi Info™ 7 – Core Principles • Free • Easy to use • Flexible • Lightweight & Agile – when responding to emergencies • Robust – when performing large-scale, multi-user data collection • Standards based • No “IT guys” needed in most cases

  14. Form Designer Used to create electronic data entry forms. Templates can be utilized to facilitate form design. The data entry experience can be tailored with intelligence, such as skip patterns, logical branching, and automatic calculations.

  15. Enter Used to collect data into the form. Addresses can be geocoded into latitude and longitude. Data entry follows the Intelligence rules tailored in the Form Designer.

  16. Classic Analysis Used for data management and analysis. Can read data, relate data tables, perform comparisons and run a wide variety of statistics. Supported data types include text files, Excel spreadsheets, Access databases, and MS SQL Server databases. Output is saved as HTML.

  17. Visual Dashboard Used for quick analysis where only minimal data management is needed. Supports almost all of the statistics as Classic Analysis and supports the same data types. Output is saved as HTML.

  18. Maps Used to create case cluster or choropleth maps. Time lapse functionality is supported. Choropleth maps can be generated using shape files or from map servers such as nationalmaps.gov.

  19. StatCalc Basic Statistical Calculator. Can perform analyses of single or stratified two-by-two tables, determine sample size for studies, and more.

  20. Epi Info™ 7 Projects • Projects are the standard file format in Epi Info™ 7, much like DOCX files are the standard file format used in Microsoft Word. • Certain Epi Info™ 7 modules can also work with data that resides in other formats. • A project may contain one or more data entry forms. These forms are created in the Form Designer module.

  21. Epi Info™ 7 Forms • Forms may have one or more pages • Each page on the form has its own “data table” • As users enter data into a form, the collected data is stored within that page’s corresponding data table

  22. How data is stored • The data you collect must be stored somewhere and in some sort of standard format. • Epi Info™ 7 collects two different types of data: • Metadata: The data that describes the number of pages in a form and the placement and size of the questions that appear on the form. • Collected data: The data that is entered into that form.

  23. How data is stored (continued) • Both metadata and collected data are stored in a single database. • Each Epi Info™ 7 project contains a “pointer” to this database. • Allowable databases include Microsoft Access and Microsoft SQL Server. • Access does not need to be installed in order to use Access databases.

  24. To sum it up… • Your Epi Info™ 7 Projects consist of two files: The project file and the database. • The database contains all of the information about how to display the form AND contains all the data entered into that form. • The project file contains a pointer to the database. • Projects may contain one or more forms. • Forms may contain one or more pages. • Each page has it’s a corresponding table in the database that stores data collected into that page.

  25. Why use Microsoft SQL Server? • MS SQL Server can collect far larger quantities of data than Access databases. • Better management tools for MS SQL Server and more powerful queries are available. • Similar to “Proc-SQL” in SAS • It’s much faster, meaning data analysis is quicker. • A free version is available – SQL Server Express • http://www.microsoft.com/sqlserver/en/us/editions/express.aspx
