Creating a Basic Frequency Table
Example data: Shoe sizes of 20 students
6, 7, 8, 6, 7, 9, 8, 7, 6, 8, 7, 9, 6, 8, 7, 6, 8, 9, 7, 8
| Shoe Size | Tally | Frequency |
|---|---|---|
| 6 | |||| | 5 |
| 7 | |||| | | 6 |
| 8 | |||| | | 6 |
| 9 | ||| | 3 |
| Total | - | 20 |
Key observations:
- Mode = 7 and 8 (both appear 6 times) - bimodal
- Total frequency = 20 ✓
- Most common sizes are 7 and 8

Practice questions for Frequency Tables
The table below shows the number of books read by students in a month: | Books read | Frequency | |---|---| | 0 | 4 | | 1 | 7 | | 2 | 11 | | 3 | 6 | | 4 | 2 | What is the mode?
Explain why the mean calculated from a grouped frequency table is described as an 'estimate' rather than an exact value.
