Example 1
easyStudents were asked how many siblings they have: 0, 1, 2, 1, 3, 1, 0, 2, 1, 1, 2, 0, 1, 3, 2. Create a frequency table and find the most common number of siblings.
Solution
- 1 Step 1: List distinct values: 0, 1, 2, 3.
- 2 Step 2: Count frequencies: 0 → 3, 1 → 6, 2 → 4, 3 → 2.
- 3 Step 3: The highest frequency is 6, for 1 sibling.
Answer
Frequency table: 0 siblings (3), 1 sibling (6), 2 siblings (4), 3 siblings (2). The most common is 1 sibling.
Frequency tables organise raw data by grouping identical values and counting them. The category with the highest frequency corresponds to the mode.
