Question

Choose one of the correct alternatives given below: [1] Assertion (A) – The series in which the observations with magnitude greater than or equal to the lower limit; and less than or equal to the upper limit of a class interval are included in the class itself, are called Inclusive Series. Reason (R) - In this series, the value of upper limit of a class never equals the value of lower limit of the next class. Alternatives - (a) Both (A) & (R) are true; and (R) is the correct explanation of (A) (b) Both (A) & (R) are true; and (R) is not the correct explanation of (A) (c) (A) is true but (R) is false (d) (A) is false but (R) is true​

Answer 1

Answer:

The option (a) is correct. A series in which upper limit of one class becomes the lower limit of the succeeding class interval is called exclusive series. In such series, the frequencies of the lower limit are included in that particular class whereas the frequencies of the upper limit are excluded.
