zeep,car,bike,bus,car,lorry,bus,lorry,bus,bike,car,zeep,bus,lorry,lorry,bus,car, car, bike, auto.  

Vehicle         Tally Marks             Frequency

Car                 $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$ |                            6

Lorry               $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$  $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$  |                   11

Bus                $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$  ||||                         9

Auto                 |||                               3

bike                  ||||                             4  

zeep                 |||                              3

Tally marks are a unary numeral system.

These are also called hash marks,

These are in  form of numeral used for counting.

a line is use to represent 1

two line for 2

three lines for 3

4 lines for 4

1  - |

2 - ||

3 - |||

4 - ||||

Making reading easier 5 is represented by crossing 4 lines

5 - $\setlength{\unitlength}{0.5cm} \begin{picture}(4,4) \multiput(2, 1)(0.2, 0){4}{\line(0, 1){0.5}} \put(1.8, 1){\line(2, 1){1}} \end{picture}$
