Question

A class test was conducted for English. The marks obtained by students are given below.

$60, 70, 80, 85, 62, 65, 66, 69, 52, 45, 24, 37, 39, 42, 44, 56, 59, 62, 72, 37, 39, 42, 45, 55, 60, 82$

Prepare a frequency table and answer the following question?

How many students got the same marks?

Accepted Answer

We have to draw a frequency table for the English marks obtained by students given below:
$60, 70, 80, 85, 62, 65, 66, 69, 52, 45, 24, 37, 39, 42, 44, 56, 59, 62, 72, 37, 39, 42, 45, 55, 60, 82$

Arranging the above marks in ascending order, we get :

$24, 37, 37, 39, 39, 42, 42, 44, 45, 45, 52, 55, 56, 59, 60, 60, 62, 62, 65, 66, 69, 70, 72, 80, 82, 85$

We shall now use the above data to construct the following frequency table:

English marks Tally marks Frequency (number of students)

$24$ $|$ $1$

$37$ $∥$ $2$

$39$ $∥$ $2$

$42$ $∥$ $2$

$44$ $|$ $1$

$45$ $∥$ $2$

$52$ $|$ $1$

$55$ $|$ $1$

$56$ $|$ $1$

$59$ $|$ $1$

$60$ $∥$ $2$

$62$ $∥$ $2$

$65$ $|$ $1$

$66$ $|$ $1$

$69$ $|$ $1$

$70$ $|$ $1$

$72$ $|$ $1$

$80$ $|$ $1$

$82$ $|$ $1$

$85$ $|$ $1$

Total: $26$ students

Now, we have to find out how many students got same marks that is how many rows have more than one entry. So here $37, 39, 42, 45, 60, 62$ marks entries have more than one student.

Therefore, number of students who got same marks are:

$= 37 \to 2$ students

$= 39 \to 2$ students

$= 42 \to 2$ students

$= 45 \to 2$ students

$= 60 \to 2$ students

$= 62 \to 2$ students
