Welcome
What are you trying to do?
Data I already have in engineering, manufacturing and quality.
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
Chart the process - establish stability - then and only then measure capability - test changes against it.
- Is my process stable?control chart
- Can it meet the specification?process capability
- Which machine, shift or operator differs?one way anova
- Two settings at once, and do they interact?factorial anova
- How long until failure?kaplan meier
Watch for: Drawing control limits from the specification. That chart cannot show the process drifting inside tolerance, which is the reason to draw it.
