## Summary of test

{% hint style="info" %}
This overview will show you the following:

* **Group** → when we do an a/b test we will be make different groups (emails, flows, etc) to find out what leads to the least amount of churners.&#x20;
* **Contacts** → the numbers revere to the amount of people that entered that group.&#x20;
* **Churn** → this will show you the amount of people that churned in their group.
* **Churn** **Rate** → this percentage will show you what percentage of people churned that entered the group.
* **Churn** **Loss** → the amount of money you lost based on the value of the people that have churned.
* **Avg.** **loss** → this is based on the following formula: *churn loss/contacts = avg. churn loss*
  {% endhint %}

$$
Churn Rate = Churners/Contacts\*100

{% hint style="info" %}
The **winner** is based on the group that had the lowest churn rate

{% hint style="info" %}
The **Churn Rate graph** is interactive. This way you can look at the development and the process of the a/b test.&#x20;

## Average Churn rate per segment

**You can view the chart in:**\
&#x20;    \- Churn Rate \
&#x20;    \- Avg. Churn Loss

### Churn Rate

{% hint style="info" %}
The **Average Churn rate per segment** will display different percentages that are based on the customers that have churned. This can display a lot of different factors like:

* **Channels** → Mail, Inbound and Website, etc.
* **Gender** → Male, Female, Neutral, etc.
* **Product** → Online, Physical, etc.
* **Client** **Type** → Individual, Subscription, etc.
* **Engagement** → Daily user, Weekly user, Monthly user, No engagement, etc.

> You can use these graphs to dive a little deeper into who the people are that churned. This will give you more insight on what there behavior was and what you should focus on to prevent churn.

### Avg. Churn Loss

<figure><img src="/files/3roTKwr3aK5hUR9mzdeh" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
The **average churn loss** is a way to show you were you will lose the most amount of money. This can help with understanding which customers are going to cost you less or more money.&#x20;

{% hint style="info" %}
You can have **multiple a/b tests**, they don't have the be live at the same time but you will be able to look back and review their results.
