# Upsample Survey Data

> Adjust the influence of individuals in your survey using a variable with predefined weights to scale your survey data.

Upsampling surveys is usually a good practice when there might be under (or over) represented
groups in your data. By using a scaling factor, we can adjust the influence each individual
has in the hopes of better representing the actual distribution, had we sampled indefinitely.

  Check out the [upsample](/api-docs/prepare/filter/upsample) step for more
  information.

## Parameters

* **Weights**: numeric column with weights representing by how much this particular row's influence should be scaled
* **Minimum number of rows**: number of rows you need to have in your dataset to ensure that the weighted representation accurately reflects the population, even considering the least influential respondent
