Objectives: This study aimed identify the predictors married women’s practice using Bayesian and classical approach. In addition, identified within between Woredas variation hierarchical nature data obtained different woredas. For identifying better model, researcher compared multilevel logistic regression models. Methods: research conducted seven Assosa zone based on cross-sectional primarily focused ages 15 49 factors influenced their use. Two stage model comparisons were approximate parameters, first having null, random intercept, slope Result Conclusion: overall among 6866 3121(45.46%). According intra Woreda correlation appropriate variance women's 15.71%, remaining 84.29 attributed differences women. Finally, such as age, place residence, educational level, husband's job, occupation, wealth index, religion, knowledge family planning. found most suitable fitting after comparison
