Question :-

The Weight of the 30 Students in a Class are given below. Complete the following Table by Tally Mark

35, 36, 33, 33, 32, 32, 35, 33, 36, 34, 34, 34, 38, 35, 32,

36,  35, 35, 32, 35, 34, 33, 32, 34, 36, 35, 35, 32, 38, 34

Solution :-

Arranging the Weights in Ascending Order of Magnitude, we get the Array as Under :-

32, 32, 32, 32, 32, 32, 33, 33, 33, 33, 34, 34, 34, 34, 34,

34, 35, 35, 35, 35, 35, 35, 35, 35, 36, 36, 36, 36, 38, 38

For Counting, we use Tally Marks $I$, $II$, $III$, $IIII$, and the Fifth Tally Mark is Entered as $\cancel {IIII}$ by Crossing Diagonally the Four Tally Marks already Entered...

-

Frequency Table is Presented as Under :

$\begin {array}{| c | c | c |} \cline {1 - 3} \bold {Weights} & \bold {Tally\: Marks} & \bold {Frequency} \\\cline {1 - 3} 32 & IIIIII & 6\\\cline {1 - 3} 33 & IIII & 4 \\\cline {1 - 3} 34 & IIIIII & 6\\\cline {1 - 3} 35 & IIIIIIII & 8\\\cline {1 - 3} 36 & IIII & 4\\\cline {1 - 3} 38 & II & 2\\\cline {1 - 3} & \bold {Total} & 30\\\cline {1 - 3} \end {array}$
