epidata software functions

EpiData is a program for entering and recording data.

Use EpiData when you collect data on paper and want to perform statistical analysis or tabulation of the data. Basic frequency tables and data lists can be made, but the focus of EpiData is on data entry and data logging.

During the data entry process, you can define aggregation scales or value limits. You can select an item from the list and save the corresponding numeric code (1 = No 2 = Yes), the text list will be exported as "Value Labels" for the statistics program. Dates are easy to enter, for example if in 2003 "dd/mm/ yyyy" field, the format will be January 23, 2003.

EpiData works for simple datasets where you have one data source (such as a questionnaire or a lab registration form), as well as datasets with many or branching data tables; only simple cases are described here. This principle is rooted in the dos program Epi Info v6 simplicity. The idea is that you write simple lines of text and then the program converts them into a data entry form to which you can add further control over entries, conditional jumps to other fields or calculations.
