# Imputation
Imputation refers to the process of **replacing missing data with substituted values.** The missing data might be filled using different statistical methods such as mean, median, or mode imputation, or even more sophisticated methods like K-nearest neighbors or predictive models to estimate the missing values based on other available information.
\
**Steps to follow:**
1. Choose the column where you want to perform the "Imputation" operation.
2. Look for the "Imputation" option within PredictEasy.
3. Select the method of Imputation such as Mean or Median.
4. Initiate the "Imputation" operation. This action triggers the imputation process.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.predicteasy.com/data-preprocessing/imputation.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
