The purpose of this research is to compare the effectiveness of various methods used in solving missing data problems in the context of validity and reliability of the scales. For this purpose PISA 2012 Turkey sample and “Math Work Ethics” scale was used. For the analysis, complete data set of 200 persons were chosen from the Turkey sample at random. After the process of data deletion at different rates from complete data set and transforming them into new complete data sets, under missing completely at random (MCAR) mechanism, analysis of validity and reliability were realized. During the phase of transforming missing data set into new complete data sets, series mean, mean of nearby points, median of nearby points, linear interpolation, linear trend at point, listwise deletion, expectation maximization, regression imputation and multiple imputation methods were used. The values obtained from the complete data set were used as reference values in interpreting the values by comparing the values of validity and reliability at the new complete data sets. The research results reveal that the values obtained for the listwise deletion at different rates of missing data are the values with the least similarity to the ones generally obtained from the complete data set. While the values obtained for the approximate value imputation methods resulted in proximal or same values as the ones generally obtained from the complete data set in cases where the missing data rate is low multiple imputation, expectation maximization and regression imputation methods resulted in close proximal values at all missing data rates as the ones obtained from the complete data set
