Abstract EN

The objective of the present study is to analysis statistical data using two different methods , data could be the weighing of children their ages four months for September 2012 .

The methodology used in this study is dependent on two different technique in analysis when analysis data using Lagrange interpolating method we obtain polynomial from third degree after suption interior and exterior values of ? it gave inverse results which indicate to decrease of weighing .

But when we use the statistical method (T test for two independents samples) , test take place around mean which to call in from it ,the sample if it is equals or not in level of signature 5% results conduce to following : 1\ Population mean which to call in from two samples it equal .

2\ The data follow to normal distribution .

3\ The data it homogenous .

We conclude that any over and above imposed mean it takes healthy problems for children .
