Which central tendency has been used to arrive at the following statements?
Mickey noticed that half of the chocolate brands in the store cost more than 22.

Answer

To determine which measure of central tendency has been used in the statement "Mickey noticed that half of the chocolate brands in the store cost more than 22," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Central Tendency**:
- Central tendency is a statistical measure that identifies a single value as representative of an entire dataset. The three main types of central tendency are mean, median, and mode.

2. **Analyzing the Statement**:
- The statement mentions that "half of the chocolate brands cost more than 22." This implies that there is a specific point (in this case, 22) that divides the dataset into two equal halves.

3. **Identifying the Type of Central Tendency**:
- The term "half" indicates that we are looking at a middle point in the data. This is characteristic of the median, which is the value that separates the higher half from the lower half of a dataset.

4. **Conclusion**:
- Since the statement refers to a point where half of the data is above and half is below, we conclude that the central tendency used here is the **median**.

### Final Answer:
The central tendency used in the statement is **median**.
