Abstract
This paper investigate the linear logarthimic models related to the analysis of the square cotengency tables in case the categories are ordered .Symmetric and simple symmetric, conditional symmetric and diagonal parameters symmetric models are investigated. These models are exploited to analyze the degree of hearing problem for exampleor asample of (500) people from Babylon and (500)people from AL-Muthana. The statistical results show that in case the hearing problem is generally symmetrical the degree of hearing capacity of the right ear is better than left one in Babylon whereas the results in AL-Muthana are the other way around.
