Question

Construct a frequency table for the following:
$7,8,6,5,6,7,7,9,8,10,7,6,7,8,8,9,10,5,7,8,7,6$

Answer 1

To construct a frequency table, we write the frequency of each number with the help of tally marks. Hence, the frequency table for the given data can be represented as follow:

$\begin{array}{ccc}\text{Observation}& \text{Tally Marks}& \text{Number}\\ 5& ||& 2\\ 6& ||||& 4\\ 7& ||||||& 7\\ 8& ||||& 5\\ 9& ||& 2\\ 10& ||& 2\end{array}$
