To find the **mean** of the given data set, follow these steps:

### **Given Data:**
$$ 12, \, 10, \, 15, \, 10, \, 16, \, 12, \, 10, \, 15, \, 15, \, 13 $$

### **Step 1: Calculate the Sum of All Data Points**
$$
12 + 10 + 15 + 10 + 16 + 12 + 10 + 15 + 15 + 13 = 128
$$

### **Step 2: Count the Number of Data Points**
There are **10** numbers in the data set.

### **Step 3: Compute the Mean**
$$
\text{Mean} = \frac{\text{Sum of all data points}}{\text{Number of data points}} = \frac{128}{10} = 12.8
$$

### **Final Answer:**
The mean of the data set is **12.8**.
The mean of the data set is 12.8.
