Find the average of the following set of scores :
432,623,209,378,908,168

Options

A. 456
B. 455
C. 453
D. 458

Explanation

To find the average of the given set of scores: 432, 623, 209, 378, 908, and 168, we will follow these steps:

### Step 1: Add all the scores together.
We will sum the numbers:
\[ 432 + 623 + 209 + 378 + 908 + 168 \]

### Calculation:
1. \( 432 + 623 = 1055 \)
2. \( 1055 + 209 = 1264 \)
3. \( 1264 + 378 = 1642 \)
4. \( 1642 + 908 = 2550 \)
5. \( 2550 + 168 = 2718 \)

So, the total sum of the scores is:
\[ 2718 \]

### Step 2: Count the total number of observations.
There are 6 scores in total:
\[ 6 \]

### Step 3: Divide the total sum by the number of observations to find the average.
Now we will calculate the average:
\[ \text{Average} = \frac{\text{Total Sum}}{\text{Number of Observations}} = \frac{2718}{6} \]

### Calculation:
1. \( 2718 \div 6 = 453 \)

Thus, the average of the given set of scores is:
\[ \text{Average} = 453 \]

### Final Answer:
The average score is **453**.
