## Abstract

This study was focus on comparing the estimation methods for missing data in simple linear regression. The methods that used to estimate missing data are Singh method and Expectation Maximization Algorithm (EM). The comparison was done under condition of sample sizes 40, 100, 500 and 1,000; variances 1, 10 and 50; percentages of missing data 5%, 10% and 15%; the correlation coefficient levels between the dependent and independent variable are -0.3, -0.6, -0.9, 0.3, 0.6 and 0.9. The criterion of determination is Root Mean Square Error (RMSE). The results show that the EM method is a better estimation method than Singh method for simple linear regression due to EM method give the lowest RMSE values for all levels of correlation coefficients, sample sizes, variances and percentages of missing data.
