To make a tally and frequency table for the number of books read by students during the summer, you need to count the number of occurrences of each number and then organize the data in a table.
Here's how you can do it step by step:
Step 1: Start by listing all the numbers from the data set: 4, 5, 7, 2, 4, 5, 6, 7, 8, 4, 5, 3.
Step 2: Create a tally for each number by drawing vertical lines. For each number in the data set, make a tally mark on its corresponding line.
4: ||
5: |||
7: ||
2: |
6: |
8: |
3: |
Step 3: Count the number of tally marks for each number and write it next to the tally marks:
4: || (2)
5: ||| (3)
7: || (2)
2: | (1)
6: | (1)
8: | (1)
3: | (1)
Step 4: Create a frequency table using the tally marks and their corresponding counts:
Number of Books Read | Frequency
4 | 2
5 | 3
7 | 2
2 | 1
6 | 1
8 | 1
3 | 1
Answer: From the frequency table, you can see that there are a total of 7 students who took part in the survey.
