Attendance records at a school show the number of days each student was absent during the year. The days absent for each student were as follows: 8 2 4 3 2 7 6 0 9 3 3 4 2 4 6
Create a dot plot for this data
Since this is not my area of expertise, I searched Google under the key words "dot plots" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
To create a dot plot for this data, follow these steps:
1. Identify the unique values in the data set: 0, 2, 3, 4, 6, 7, 8, 9.
2. Draw a horizontal axis to display the possible values.
3. Place a dot above each value on the axis corresponding to the number of days absent.
4. Repeat the process for each value in the data set.
Here is the dot plot for the given data:
```
0: •
2: ••••
3: •••
4: •••
6: ••
7: •
8: •
9: •
```
In this dot plot, the numbers represent the number of days absent, and the dots indicate the frequency of each value.
To create a dot plot for the given data, you need to follow these steps:
1. First, list all the different values in the data set. In this case, the different values of days absent are 0, 2, 3, 4, 6, 7, 8, and 9.
2. Draw a number line that spans the range of the data. In this case, the range is from 0 to 9.
3. Mark each of the values from the data set on the number line.
4. Create a grid that extends vertically from the number line.
5. Use dots or other symbols to represent each instance of a particular value. For example, if there are two students who were absent for 2 days, place two dots above the number 2 on the number line.
6. Continue placing dots above the number line for each value, depending on how many times it occurs.
Here is the dot plot for the given data set:
Number of Days Absent:
0 (1 dot)
1
2 (4 dots)
3 (3 dots)
4 (3 dots)
5
6 (2 dots)
7 (1 dot)
8 (1 dot)
9 (1 dot)
Each dot represents one instance or student in this case, so the height of the dots helps visualize the frequency or number of students for each value.
