Math worksheet for students to practice creating frequency tables using tally marks based on survey data about the number of siblings among 50 children.

I'll solve this frequency table problem step by step.

First, let me count how many times each number of siblings appears in the data:

The data given is:
3, 3, 2, 1, 1, 0, 2, 3, 4, 2, 3, 2, 5, 4, 1, 1, 4, 2, 3, 2, 2, 2, 3, 1, 3, 4, 5, 1, 2, 2, 3, 0, 1, 1, 3, 3, 2, 1, 4, 3, 2, 4, 1, 1, 2, 2, 3, 2, 3

Let me count each value carefully:

Number of children with 0 siblings:
Looking through the data: I see "0" appears twice (positions 6 and 32)
Count = 2

Number of children with 1 sibling:
Looking through: 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1
Let me count more carefully: positions 4, 5, 15, 16, 24, 28, 33, 34, 38, 43, 44
That's 11 ones
Count = 11

Number of children with 2 siblings:
Looking through: 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2
Let me count: positions 3, 7, 10, 12, 18, 20, 21, 22, 29, 30, 37, 41, 45, 46, 48
That's 15 twos
Count = 15

Number of children with 3 siblings:
Looking through: 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3
Let me count: positions 1, 2, 8, 11, 19, 23, 25, 31, 35, 36, 40, 47, 49
That's 13 threes
Count = 13

Number of children with 4 siblings:
Looking through: 4, 4, 4, 4, 4, 4, 4
Let me count: positions 9, 14, 17, 26, 39, 42
That's 6 fours
Count = 6

Number of children with 5 siblings:
Looking through: 5, 5
Positions 13, 27
That's 2 fives
Count = 2

Let me verify: 2 + 11 + 15 + 13 + 6 + 2 = 49... that should be 50!

Let me recount more carefully by going through the entire list systematically:

3, 3, 2, 1, 1, 0, 2, 3, 4, 2, 3, 2, 5, 4, 1, 1, 4, 2, 3, 2, 2, 2, 3, 1, 3, 4, 5, 1, 2, 2, 3, 0, 1, 1, 3, 3, 2, 1, 4, 3, 2, 4, 1, 1, 2, 2, 3, 2, 3

Going through one by one:
- 0s: position 6, position 32 → 2 zeros
- 1s: positions 4, 5, 15, 16, 24, 28, 33, 34, 38, 43, 44 → 11 ones
- 2s: positions 3, 7, 10, 12, 18, 20, 21, 22, 29, 30, 37, 41, 45, 46, 48 → 15 twos
- 3s: positions 1, 2, 8, 11, 19, 23, 25, 31, 35, 36, 40, 47, 49 → 13 threes
- 4s: positions 9, 14, 17, 26, 39, 42 → 6 fours
- 5s: positions 13, 27 → 2 fives

Total: 2 + 11 + 15 + 13 + 6 + 2 = 49

Wait, there should be 50 children. Let me count the total numbers in the data again. Looking at the original data more carefully - it appears to be arranged in rows. Let me count all the numbers:

Row 1: 3, 3, 2, 1, 1, 0, 2, 3, 4, 2 (10 numbers)
Row 2: 3, 2, 5, 4, 1, 1, 4, 2, 3, 2 (10 numbers)
Row 3: 2, 2, 3, 1, 3, 4, 5, 1, 2, 2 (10 numbers)
Row 4: 3, 0, 1, 1, 3, 3, 2, 1, 4, 3 (10 numbers)
Row 5: 2, 4, 1, 1, 2, 2, 3, 2, 3 (9 numbers)

Total: 10 + 10 + 10 + 10 + 9 = 49 numbers

Hmm, but the problem says 50 children. Let me look at the image again... Actually, looking more carefully at row 5, I need to recount. The last row shows: 2, 4, 1, 1, 2, 2, 3, 2, 3 - that's only 9 numbers. But wait, maybe I'm misreading the layout.

Let me try a different approach - I'll just count directly from what I can see in the data string provided:

Actually, re-examining the data more carefully, I notice there might be an issue with how I'm reading it. Let me work with what I have and double-check my counts are correct for the visible data.

My counts were:
- 0 siblings: 2
- 1 sibling: 11
- 2 siblings: 15
- 3 siblings: 13
- 4 siblings: 6
- 5 siblings: 2

Total: 49

Since the problem states 50 children but I'm counting 49 data points, there may be a transcription issue. However, based on the data provided, these are my accurate counts.

For tally marks:
- Each group of 5 is represented as four vertical lines with a diagonal line through them (||||/)
- Remaining marks are shown as vertical lines

Final Answer:

| # of Siblings | Tally Marks | Frequency |
|---------------|-------------|-----------|
| 0 | || | 2 |
| 1 | ||||/ ||||/ | | 11 |
| 2 | ||||/ ||||/ ||||/ | | 15 |
| 3 | ||||/ ||||/ ||| | 13 |
| 4 | ||||/ | | 6 |
| 5 | || | 2 |
