Welcome
What are you trying to do?
Something I need to watch regularly in education.
Before you start. Monitors currently run from the command line rather than from a page. The engine works and is tested; the interface for setting them up is still being built, so this route is the least finished of the four.
Your path
01
Create the study
One study holds the whole series.
02
Chart it before you judge it
A control chart separates ordinary variation from a real change. Most month-to-month movement is noise, and acting on it makes a process less stable rather than more.
03
Set up a monitor
A saved analysis with a cadence. It re-runs and reports what moved, without claiming the movement is significant - two consecutive estimates are not independent samples.
04
Read the series, not the last point
Twelve points tell you what one never can.
What people in your field ask

Define the outcome - account for the school or class - compare or predict - check the test itself.
- Did the new teaching method improve scores?independent t
- Students are inside classes inside schools. Does that matter?multilevel mixed
- What predicts performance?ols regression
- Is my test any good?irt 2pl
- Does the questionnaire work the same across programmes?measurement invariance
Watch for: Analysing at the student level a treatment that was assigned to whole classes.
