To solve the problem, we need to find the mean, median, and mode for the given student attendance data. The data provided shows the number of students absent each day from December 3–7:

- Monday: 4 students
- Tuesday: 3 students
- Wednesday: 1 student
- Thursday: 4 students
- Friday: 5 students

### Step 1: Calculate the Mean
The mean is the average number of students absent. To find it, sum all the values and divide by the number of days.

\[
\text{Mean} = \frac{4 + 3 + 1 + 4 + 5}{5} = \frac{17}{5} = 3.4
\]

### Step 2: Find the Median
The median is the middle value when the data is arranged in ascending order. The sorted data is: 1, 3, 4, 4, 5.

Since there are 5 values, the median is the third value in the sorted list, which is 4.

### Step 3: Determine the Mode
The mode is the value that appears most frequently. In the data set, the number 4 appears twice, while all other values appear once.

Therefore, the mode is 4.

### Summary
- **Mean:** 3.4
- **Median:** 4
- **Mode:** 4

1. How would the mean, median, and mode change if one more day of data were added?
2. What happens to the median if the data set contains an even number of observations?
3. How does the presence of outliers affect the mean, median, and mode?
4. Can a data set have more than one mode, and what is it called in that case?
5. How can you estimate the range and standard deviation of this data set?

### Tip:
When calculating the median for an even number of data points, average the two middle numbers.
