Question
Explain the definition of inclusive continuous frequency distribution.
✓
Answer
If the upper limit of a class and lower limit of succeeding class are not equal and the upper limit of a class is included in that class, then such classes are called inclusive type of classes. A continuous frequency distribution consists of inclusive type classes is called inclusive continuous frequency distribution.
Explanation : The frequency distribution consists of classes $10— 19, 20— 29, 30—39$ ... is inclusive continuous frequency distribution. Here, the upper limit $29$ of class $20—29$ and the lower limit 30 of its succeedmg class $30—39$ are not equal. Also upper limit $29$ is included in the class $20—29.$
