Make a tally chart for the numbers of students in the third-,fourth-,and fifth-grade classes:26,25,27,27,26,28,27.
The abscissa would range from 25-28 with tallies ranging from 1 to 3 in each value.

To create a tally chart for the numbers of students in the third, fourth, and fifth-grade classes, you can follow these steps:
1. Start by drawing a table with two columns. Label the left column as "Numbers" and the right column as "Tally Marks".
2. Write down the numbers from the given list in the "Numbers" column of the table. So, the numbers in the list are: 26, 25, 27, 27, 26, 28, 27.
3. For each number, make a tally mark in the "Tally Marks" column. Each tally mark represents one student. Start with a vertical line for the first mark.
- For the number 26, draw a vertical line.
- For the number 25, draw another vertical line next to the previous one and cross the first line with a diagonal line. This represents the fifth tally mark.
- For the number 27, draw a diagonal line across the fourth tally mark.
- For the number 27 (again), draw another diagonal line across the fourth tally mark but in the opposite direction.
- For the number 26 (again), draw a diagonal line across the second tally mark.
- For the number 28, draw a vertical line next to the previous one, crossing all the previous tally marks.
- For the number 27 (again), draw a diagonal line across the sixth tally mark.
4. Count the number of tally marks for each number to find the frequency, which represents the number of students in each grade. In this case, the tally marks will represent the following frequencies:
26: |||
25: |
27: |||.
28: |
5. Finally, you can summarize the information in a more organized way, presenting the frequencies in a chart:
Numbers | Tally Marks
--------|------------
26 | |||
25 | |
27 | |||.
28 | |
That's how you can create a tally chart showing the number of students in the third, fourth, and fifth-grade classes based on the given data.
