EXERCISE
1. Create an EpiData folder on your Desktop.
Creating your .qes file
2. Create a new questionnaire file (.qes) and name it ebolascreen1.qes.
3. Type the title of your form (i.e. Ebola Screening Questionnaire) at the top of your new blank form.
4. Add your field names.
Begin recreating the form that appears on the previous page. Remember you will be creating
custom field names using curly brackets - e.g. If we want the variable name for the field ‘Interviewer
initials’ to appear as ‘intin’ we will need to write {Int}erviewer {in}itials as the field name in EpiData.
Please make sure when creating your form that you use curly brackets to create the following field
names. NOTE: Make sure your field names are EXACTLY as shown and use the preview
button to check your work!

5. Add editable fields.
Add your editable fields manually or using the FIELD PICK LIST button.
6. Add notes to help with data entry.
When you create a data entry form it is nice to have some guidance for those doing the data entry.
e.g. If you are recording cause of death and are using numerical values to denote individual causes it
would be better to provide a guide on the form so that it’s clear which values will be accepted.
When creating your form include some indication of which values will be accepted.
The easiest way to insert editable fields is to place your
cursor where you would like to insert the editable field
and then click the FIELD PICK LIST button

Creating your .rec file
7. Generate a data entry (.rec) file and name it ebolascreen1.rec.
Creating your .chk file
8. Create a check file (.chk) and name it ebolascreen1.chk.
9. Apply all checks indicated on the above survey.
10. Create value labels and ask EpiDATA to display the associated label.
HINT: You will use the ‘type comment’ command.
11. Apply all jumps indicated in the above survey.
Data entry
12. Duplicate your .qes and .rec files, put them in another folder, and rename them ebolascreen2.rec
and ebolascreen2.chk
13. Enter the data from Questionnaires 1-6 on the following pages.
14. Close your .rec file and save.
Double entry
15. Open ebolascreen2.rec and enter the data from Questionnaires 1-6 again – but make a few errors!
16. Compare your ebolascreen1.rec with your ebolascreen2.rec and navigate to the errors – you may
correct any errors at this point.
Exporting to STATA
17. Export your ebolascreen1.rec file to STATA (.dta) format.
18. Open the file in STATA and use the data editor (browse) to check that your data have exported
properly.
