# Weighting

```yaml
weighting: 100
```

A positive value represents the weighted average. The higher this value is compared to other biomes of the same climate, the more prominent it becomes in the world.

{% hint style="info" %}
The **weighted average** is a way to calculate an average in which different values are given different importance or "weights."
{% endhint %}

In simple terms, it's a way of finding the overall average by taking into account how much each value contributes to the final result.

So, the weighted average gives more importance to values with higher weights, so they have a greater impact on the final average. This is useful in situations where some values are more significant or relevant than others when calculating an average.

For example, let's consider three biomes

* DARK\_FOREST=50
* FOREST=100
* PLAINS=5

You can visualize the weighted average as follows:

In this manner, you can create extremely rare biomes like mushroom biomes or very common ones like forests.

{% hint style="info" %}
**Minimum value**: 1

**Maximum value**: infinite
{% endhint %}
