Welcome
What are you trying to do?
Data I already have in agencies, ngos and programme evaluation.
Your path
Create a study to hold it
A study is the container. You are not obliged to collect anything through ZStat.
Import the file
CSV for now, on the Data page. Leading zeros survive, and a column that is mostly numeric with a few words stays text rather than becoming numbers with holes in it.
Find out what you should be running
The guide for your field names the question in your own words and the procedure that answers it.
Analyse
Every result is stored with the digest of the data behind it, so you can prove later which version produced which figure.
What people in your field ask
Define the indicator - sample defensibly - collect with consent - compare against baseline - report what the design can and cannot support.
- Did the programme change anything?independent t
- We could not randomise. Can we still claim an effect?propensity matching
- How many people are affected, and how sure are we?survey proportion
- Our survey used clusters. Does that change the numbers?survey mean
- Which communities are worst affected?getis ord
Watch for: Reporting a before-and-after difference as programme impact when anything else changed in the same period.
