A frequency distribution is given below: Classes: 10-20, 20-30, 30-40, 40-50, 50-60 Frequency: 12, 18, 10, 5, 2. The class which has minimum frequency is?
Answer: 50-60
Explanation
Given frequencies:
10–20 → 12
20–30 → 18
30–40 → 10
40–50 → 5
50–60 → 2
The minimum frequency is 2, which corresponds to class 50–60.
