• Why do we need the Multilevel Modeling?
• When do we need the Multilevel
Modeling?
• How can we conduct the Multilevel
analysis?

18. A simple question
How much of the variability in pupil attainment is attributable to
schools level factors and how much to pupil level factors?
First of all we have to define what we mean by “variability”
23. Returning to our question
How much of the variability in pupil attainment is attributable to
schools level factors and how much to pupil level factors?
In terms of our example we can now say
6/7= 86% of the total variation of pupils attainment is
attributable to school level factors
1/7= 14% of the total variation of pupils attainment is
attributable to pupil level factors
