N2  - One of the problems in survey is often experienced is there are some units that do not
respond to some of the questions so that it makes data are incomplete or data are
missing. Imputation method is one of the ways to overcome the missing data. Mean
imputation and K Nearest Neighbor Imputation are two method that can be used to
this research. The purpose of the research is to compare the imputation method to
estimate the missing data with Mean Imputation and K Nearest Neighbor (KNN)
Imputation and search which method is better among two methods. Based on
simulation study with 1000 replication KNN Imputation method has a smaller the
average value of Mean Square Error (MSE) and Mean Absolute Percentage Error
(MAPE) than Mean Imputation. Therefore, it is concluded that KNN Imputation
method is better than Mean Imputation Method.
Keywords : Missing Data, Imputation, Mean Imputation, K Nearest Neighbor
