Find the average of following set of scores
834, 631, 726, 152, 334, 263

Options

A. 490
B. 348
C. 520
D. 450

Answer

To find the average of the given set of scores, we will follow these steps:

### Step 1: List the Scores
The scores provided are:
- 834
- 631
- 726
- 152
- 334
- 263

### Step 2: Calculate the Sum of the Scores
We will add all the scores together:
\[ 834 + 631 + 726 + 152 + 334 + 263 \]

Calculating step-by-step:
- First, add 834 and 631:
\[ 834 + 631 = 1465 \]
- Next, add 726:
\[ 1465 + 726 = 2191 \]
- Then, add 152:
\[ 2191 + 152 = 2343 \]
- Now, add 334:
\[ 2343 + 334 = 2677 \]
- Finally, add 263:
\[ 2677 + 263 = 2940 \]

So, the total sum of the scores is:
\[ \text{Sum} = 2940 \]

### Step 3: Count the Number of Observations
Count the number of scores:
- There are 6 scores in total.

### Step 4: Calculate the Average
Now, we will use the formula for average:
\[ \text{Average} = \frac{\text{Sum of all observations}}{\text{Number of observations}} \]
Substituting the values we found:
\[ \text{Average} = \frac{2940}{6} \]

Calculating the division:
\[ 2940 \div 6 = 490 \]

### Final Answer
The average of the given set of scores is:
\[ \text{Average} = 490 \]
