Welcome
What are you trying to do?
Data I already have in public health and epidemiology.
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 population - sample it - describe with weights - compare groups - map the pattern - report the denominator.
- How common is it, and how confident are we?survey proportion
- Does it differ between districts, sexes or age bands?chi square independence
- Our survey used clusters and weights. Does that change anything?survey mean
- Is the disease clustered in particular places?morans i
- Where exactly are the hot spots?getis ord
Watch for: Comparing rates across sites without checking the denominator means the same thing in both. Most disputes about a rate are disputes about the denominator.
