I see the task you uploaded. Let's break it down.

The data set provided is:
\[ 7, 7, 8, 10, 2, 5, 5, 12, 5, 9 \]

### 1. **Antal observationer (Number of observations)**:
The number of values in the dataset is 10.

### 2. **Gennemsnit (Mean)**:
The mean is calculated by adding all the values and then dividing by the number of observations.

\[
\text{Mean} = \frac{7 + 7 + 8 + 10 + 2 + 5 + 5 + 12 + 5 + 9}{10}
\]

### 3. **Typetal (Mode)**:
The mode is the value that appears most frequently in the dataset.

### 4. **Median**:
The median is the middle value when the numbers are arranged in ascending order. Since there are 10 values, the median is the average of the 5th and 6th values.

I'll calculate these now.Here are the calculated descriptors for the dataset:

1. **Antal observationer (Number of observations):** 10
2. **Gennemsnit (Mean):** 7.0
3. **Typetal (Mode):** 5
4. **Median:** 7.0

Let me know if you'd like more details on any part of the solution, or if you have further questions. 

### Related Questions:
1. What happens if there is more than one mode in the dataset?
2. How is the median affected if there is an odd number of observations?
3. Can you identify a situation where the mean and median would differ significantly?
4. How does the presence of outliers affect the mean and median?
5. What methods can be used to describe the spread of the data?

#### Tip:
When calculating the median for an even number of observations, always take the average of the two middle values.
