# Row-level weights

> Applying weights in Caplena Reports

If you are using weighting to balance your sample, you can apply a weight variable directly in Caplena's reporting. Once applied, all results displayed in the report will automatically reflect the specified weighting.

## Applying weights to a report

You can apply weights during the report creation process via **Advanced settings**.

  <Step>
    Go to **Reports → Create new report**
  </Step>

  <Step>
    Select the template you want to use
  </Step>

  <Step>
    Expand **Advanced settings**
  </Step>

  <Step>
    Under **Select the Weight column**, choose the column containing your numeric weights
  </Step>

  <Step>
    Create the report
  </Step>
</Steps>

After the report is created, Caplena automatically incorporates the chosen weights into all displayed metrics and shows a confirmation banner at the top of the report.

<Note>
  Once a report is created, the weight column cannot be added or changed. If you need a version without weights, create a new report using the same setup but leave the weight column unselected.
</Note>

## The weight variable must be numerical

Caplena requires the weight column to be numerical. When importing your data, make sure the column is set as a numerical type — this happens automatically if it contains only numerical values.

<Note>
  Additional weighting-related features and improvements may be introduced in future updates.

## How rounding works when weighting is applied

When weighting is applied, each respondent receives a weight value — often a decimal (e.g., 0.7, 1.2, 2.3), which means counts can naturally include decimal numbers. Caplena handles this in two ways:

**Displayed counts are rounded**

All counts shown in the UI (charts, tooltips, key figures) are rounded to whole numbers to avoid confusing values like 0.4 or 7.8 respondents.

**Calculations use full precision**

Behind the scenes, all analytics use the full precise weighted decimals, including for frequencies, percentages, category and topic totals, correlations, drivers, and significance tests.
