Which method for handling missing data involves using algorithms like k-NN to find similar records to impute the missing value?

  • Mean imputation
  • Median imputation
  • k-NN imputation
  • Mode imputation
k-NN imputation is a technique that uses the similarity of data points to impute missing values. It finds records with similar characteristics to the one with missing data and replaces the missing value with the imputed value from its nearest neighbors. Other options are simpler imputation methods.
