Question

how to convert the dis-continuous class into continuous class interval

Answer 1

To make discontinuous class intervals continuous :

1. first find the class size of a range. For ex. the class size is 1.

2. Then divide the class size by 2. In this case the ans will be 0.5.

3. Now once you have divded the class size by 2 subtract your ans from the small no. of the range and add the ans on the bigger no. of the range. In this case subtract 0.5 from the smaller no. of the range and the add 0.5 to the big no. of the range.

3. Continue this step till the last range .

4. You will get the continuos class intervals.

Hope this will help you....

Answer 2

Here is your answer mate..✔✔✌

Discontinuous class interval means frequency distribution is in inclusive form .

Hence to convert it into exclusive form ,subtract 0.5 from the lower limit of the class and add 0.5 to the upper limit of the class.

For example:-

Inclusive form - 10-17,18-25,26-33,34-41

Exclusive form - 9.5-17.5,17.5-25.5,25.5-33.5,33.5-41.5
