Just for your info, Epi-data is the data management software into which you enter data, after developing a data entry template, and after data entry completed you need to export it into any statistical data analysis software (e.g. SPSS), STATA or SAS) to run the actual analysis.
jika data tidak menggunakan epi-data dan langsung dimasukkan ke program SPSS atau stata, maka tidak ada perbedaan yang berarti. data bisa langsung di input ke program atau ke excel sebelum ke program SPSS.
In addition to what mentioned by Berhanu, in Epi-data you can easily view and monitor your data and make sure the template is fit to your questionnaire.
