Answer 1

Let's calculate the mean, median, mode, and range for the list of values: 1, 2, 4, 7.

### Mean
To find the mean, sum all the values and divide by the number of values:

\[
\text{Mean} = \frac{1 + 2 + 4 + 7}{4} = \frac{14}{4} = 3.5
\]

### Median
To find the median, first, arrange the values in order (they are already in order here):

1, 2, 4, 7

Since there is an even number of values, the median is the average of the two middle values (2 and 4):

\[
\text{Median} = \frac{2 + 4}{2} = \frac{6}{2} = 3
\]

### Mode
The mode is the value that appears most frequently. In this dataset, each number appears exactly once, so there is no mode.

\[
\text{Mode} = \text{None}
\]

### Range
To find the range, subtract the smallest value from the largest value:

\[
\text{Range} = 7 - 1 = 6
\]

### Summary
- **Mean**: 3.5
- **Median**: 3
- **Mode**: None
- **Range**: 6

These values correspond to the calculated statistics for the given list.
