Find the range of the following set of scores `25,15,40,27,25,23 and 42.`

Options

A. 37
B. 27
C. 32
D. 25

Answer

To find the range of the given set of scores \(25, 15, 40, 27, 25, 23, 42\), we can follow these steps:

### Step 1: Identify the highest and lowest scores
First, we need to determine the highest and lowest values in the set of scores.

- The highest score is \(42\).
- The lowest score is \(15\).

### Step 2: Apply the range formula
The formula for calculating the range is:

\[ \text{Range} = \text{Highest score} - \text{Lowest score} \]

### Step 3: Substitute the values into the formula
Now, we substitute the highest and lowest scores into the formula:

\[ \text{Range} = 42 - 15 \]

### Step 4: Calculate the range
Now, we perform the subtraction:

\[ \text{Range} = 42 - 15 = 27 \]

### Final Answer
Thus, the range of the given set of scores is \(27\).
