EpiData software is simple QES file REC file CHK file All files are simple straight text (ASCII) files!
EpiData software is stable oIt will rarely crash (only when the operating system is jeopardized) oIf it crashes, you will only loose the one record on which you are currently working
EpiData software is speedy oAlmost as fast as Epi Info 6 oTwice as fast as Epi Info 2 K
EpiData software is sufficient oData quality: assurance through CHK files and double-entry validation oDocumentation: document every step in data entry and analysis oSafety: Rijndal (AE) encryption
EpiData software is freely available at: www.epidata.dk EpiData Entry (967 KB) EpiData Analysis (1.87 MB)
What is this course about? To demonstrate how data quality can be assured: oBy using checks to control data entry oBy working together oBy validating content through double entry and comparison
Double-entry and validation is possible with a spreadsheet, but… =IF(B4=F4,"","Discordant")
…the spreadsheet does it variable by variable, EpiData efficiently only by discordant record
