🎯 What Is a Class Midpoint?
A class midpoint is the center value of a class interval.
It is used in statistics to:
Summarize grouped data
Build frequency tables
Calculate averages (mean)
📌 Formula:
👉 Midpoint = (Lower Limit + Upper Limit) ÷ 2
This calculator applies the formula instantly and shows each step.

👉 Mean = Σ(f × Midpoint) ÷ Σf
This is useful for:
Grouped data analysis
Exam questions
Statistics assignments
📊 Example (Student-Friendly)
Single Interval Example:
Lower Limit = 60
Upper Limit = 69
👉 Midpoint = (60 + 69) ÷ 2 = 64.5
Multiple Intervals Example:
| Class Interval | Frequency | Midpoint | f × Midpoint |
|---|---|---|---|
| 60–69 | 10 | 64.5 | 645 |
| 70–79 | 12 | 74.5 | 894 |
👉 Σf = 22
👉 Σfx = 1539
📌 Weighted Mean = 69.95
