Randomized sample country s representative
Sampling technique used : Two degrees Cluster with proportional representation\methodology used by W.H.O. for the vaccine evaluation (PEV)
Unit of random = household
4
TunPR Amman March 05
Conditions of inclusion
Family with a minimum one child under 5 years
Even the study is related to 0 14 years old children, the range 0 5 is more concerned (more indicators interested in) and less represented in Tunisia (ages pyramid)
TunPR Amman March 05
We dived the country into 7 areas
6 geographical regions (EN, WN, EC, WC, ES, WS) ; plus The great Tunis (special area) = 7
Each region will be represented by a typical province
5
TunPR Amman March 05
In each region:
We select at random 30 clusters = imada
In each region we calculated the number of necessary subjects n
TunPR Amman March 05
How did we calculated n : first version
n = z² x (pq / i²) x kZ = 1.96 (confidence 95% )
P= 0.5 (unknown)
i = 7 %
K (cluster factor) = 2
5 % increase to avoid eventual refuse
6
TunPR Amman March 05
First version
n = 450
cluster s size = 15 households
Total 450 x 7 = 3150
TunPR Amman March 05
It will be time and resources consuming
One month with three teams for each region
Means 3 vehicles and oil for each region : no region can provide / no transport budget planned
7
TunPR Amman March 05
Second version
i = 10 %
n = 210
30 clusters with 7 households each one
Total = 1470
TunPR Amman March 05
That means
Only one team and one vehicle for each region during a month : possible
8
TunPR Amman March 05
Arguments
Less precise at a regional level but enough in the national level: gives the same quality with lower number
Less costly
Higher quality of information : questionnaire time consuming (boring)
