Example 1
easyA class recorded the number of pets owned by each student: 0, 1, 1, 2, 3, 1, 0, 2, 4, 1. Organise this data into a frequency table.
Solution
- 1 Step 1: List the distinct values in order: 0, 1, 2, 3, 4.
- 2 Step 2: Count how many times each value appears: 0 → 2, 1 → 4, 2 → 2, 3 → 1, 4 → 1.
- 3 Step 3: Present in a table with columns 'Number of Pets' and 'Frequency'.
Answer
Frequency table: 0 pets → 2, 1 pet → 4, 2 pets → 2, 3 pets → 1, 4 pets → 1.
Organising raw data into a frequency table makes it easier to see patterns such as the most common value and the spread of the data.
