Consider the following data.

12,−6,−7,−9,4,0

Step 1 of 3 :  Determine the mean of the given data.

To determine the mean of the given data set, we need to follow these steps:

1. **Add all the numbers together.**
2. **Divide the sum by the total number of data points.**

Given dataTo determine the mean of the given data set, we need to follow these steps:

1. **Add all the numbers together.**
2. **Divide the sum by the total number of data points.**

Given  \( 12, -6, -7, -9, 4, 0 \)

### Step 1: Add the numbers together

\[
12 + (-6) + (-7) + (-9) + 4 + 0 = 12 - 6 - 7 - 9 + 4 + 0 = -6
\]

### Step 2: Divide the sum by the number of data points

There are 6 data points in total.

\[
\text{Mean} = \frac{-6}{6} = -1
\]

So, the mean of the given data is \(-1\).
