Double-entry is a method where two people independently enter the same data to check for errors. Frequency analysis can reveal any unusual patterns or values in the data, such as a value appearing much more frequently than expected. These methods can help detect errors such as mistyping a number on a Likert scale. Analysis of variance and regression are statistical methods that can't identify such errors.
