Paragraph: Read the following information and answer: Consider the following statements : 1. Modal value of the marks in Physics lies in the interval 30-40 . 2. Median of the marks in Physics is less than that of marks in Mathematics. Which of the above statements is/are correct?

Options

  1. A1 only
  2. B2 only
  3. CBoth 1 and 2
  4. DNeither 1 nor 2

Correct answer

A. 1 only

Step-by-step solution

(1) Modal value of the marks of Physics is the interval in which maximum number of students got his marks. In the marks interval of ( 30-40) , number of students in Physics is 30 , which is largest number of students in any interval. Hence, modal values of marks in Physics is (30-40). Statement (1) is correct. (2) Median class is given by ( N 2 )^ th item i.e. ( 100 2 )^ th item which is 50th item. This corresponds to the class interval of (40-50) for Physics and (30-40) for Mathematics. aligned & Medium =l₁+ N 2 -
