Find the average of following set of scores
32, 73, 39, 29, 88, 22, 33, 64

Options

A. 483
B. 438
C. 45.7
D. 47.5

Answer

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

**Step 1: List the scores.**
The scores given are: 32, 73, 39, 29, 88, 22, 33, 64.

**Step 2: Calculate the sum of the scores.**
We will add all the scores together:
\[ 32 + 73 + 39 + 29 + 88 + 22 + 33 + 64 \]

Calculating this step-by-step:
- \( 32 + 73 = 105 \)
- \( 105 + 39 = 144 \)
- \( 144 + 29 = 173 \)
- \( 173 + 88 = 261 \)
- \( 261 + 22 = 283 \)
- \( 283 + 33 = 316 \)
- \( 316 + 64 = 380 \)

So, the total sum of the scores is \( 380 \).

**Step 3: Count the total number of scores.**
There are 8 scores in total.

**Step 4: Divide the sum by the total number of scores to find the average.**
Now, we will divide the sum by the number of scores:
\[ \text{Average} = \frac{\text{Sum of scores}}{\text{Total number of scores}} = \frac{380}{8} \]

Calculating this:
\[ \frac{380}{8} = 47.5 \]

**Final Answer:**
The average of the given set of scores is \( 47.5 \).
