Optimizely Analytics lets you create parameters for all explorations and model artifacts.

To demonstrate the procedure, consider creating parameters within a cohort.

:::hint{type="info"}
**Note**

The procedure to create parameters is the same for all artifacts and explorations.
:::

## Create a parameter within model artifacts[​](https://app.netspring.io/documentation/docs/Build%20Visualizations%20and%20Dashboards/parameters#creating-a-parameter-within-model-artifacts)

1. Click **+** > **Cohort** on the navigation panel.
2. Choose a cohort template, such as the **Behavioral** template.
3. Use the drop-down list to select a dataset for the Cohort Of field. This example uses the **Users** dataset.
4. Configure the **Behavioral Cohort** block to say **Users** who performed a particular set of product interactions: **Play Content**, **Pause Content**, **Rate Content**, and **Share Content**.
5. Configure the parameters. To create a parameter, click the pull-out drawer and click **+**. The **Creating Parameter** window displays, and you can configure your parameters. For the example, create a parameter based on **language**. Give the parameter a name, choose the column **lang** from the drop-down list, select the parameter type (***Multi Select***), and set the default value to **All**.
6. Click **Create Parameter**.

7. Go back to the cohort definition and add a filter to the cohort definition. Select a value from the drop-down list (**lang**) and choose the parameter you created from the **Parameters** tab.
8. Click **Run**. The Parameters icon in the Visualization window lets you filter your results based on the configured parameter.
9. (Optional) Give your cohort a name and description. **Save** the cohort.

## Use parameters inside Explorations[​](https://app.netspring.io/documentation/docs/Build%20Visualizations%20and%20Dashboards/parameters#using-parameters-inside-explorations)

You can use your new parameter inside an exploration with a funnel.

1. Go to **Explorations** on the navigation panel and choose **Funnel**.
2. [Configure your funnel](https://support.optimizely.com/hc/en-us/sections/34053121529357-Funnel) and add the stages.
3. Go to **Segment by Cohort** and click **+**. Choose the cohort for which you configured parameters.
4. Run the exploration. The Parameters icon in the Visualization window lets you filter your results based on the configured parameter.
5. (Optional) Add new parameters within explorations using the pull-out drawer and use them inside the **Filters** section.
