# Analyze frequent values {: #analyze-frequent-values }

In this tutorial, you'll learn how to use the Frequent Values chart, a histogram that shows the number of rows containing each value of a feature. You can also see the percentage of rows where the target is a particular value.

## Takeaways {: #takeaways }

This tutorial shows how to:

* Access and analyze the Frequent Values chart
* View average target values

## Analyze frequent values {: #analyze-frequent-values_1 }

Use the Frequent Values chart to compare the values of a feature.

1. [Import your dataset](import-data/index).

    The sample dataset featured in this tutorial contains patient data.

    The goal is to predict the likelihood of patient readmission to the hospital. The target feature is `readmitted`.

    ??? tip
        See the [Assess data quality during EDA](assess-data-quality-eda) tutorial to learn how to use the Data Quality Assessment tool.

2. In the **Project Data** list, click a feature.

     For some features like categorical and boolean features, the **Frequent Values** tab is the default. For numeric features, the **Frequent Values** tab is to the right of the **Histogram** tab.

     The Feature Values chart displays each value that appears in the dataset for the feature and the number of rows with that value:

      For the `admission_type_id` feature, the most common values are *Emergency* and *Urgent*.

## View average target values {: #view-average-target-values }

After you kick off EDA2, you can also view the average target values for features.

1. Under **What would you like to predict**, enter your target feature.


2. Click **Start**.

     As soon as DataRobot finishes analyzing features, you can view the average target values in the Frequent Values chart.

3. In the **Project Data** list, select the feature you are analyzing.

    Notice the orange circles that overlay the histogram. The circles indicate the average target value for a bin.
