Question

The number of notebooks sold on $25$ different days from a school stationery store is given below.

$3, 4, 1, 7, 5, 6, 6, 1, 2, 2, 2, 8, 6, 4, 3, 6, 7, 2, 1, 7, 6, 8, 9, 10, 4$

Represent the above information in a table using tally marks.

Accepted Answer

Procedure to create a frequency distribution table using tally marks:

(i) Make a table with three columns.

(ii) List the data in the first column.

(iii) The second column is for tally marks. Count the number of times each data value occurs in the given data set and write the tally marks accordingly.

(iv) The third column is for frequencies. Count the tally marks in the second column for each data value and write the corresponding frequency in the third column.

Thus, we get the frequency distribution table as given below:

$1$ $| | |$ $3$

$2$ $| | | |$ $4$
