Question

The distances (in 100 metres) covered by 40 students from their residence to their school were found as follows :
6 4 15 20 25 10 14 8 12 3
19 10 12 17 18 15 32 18 16 6
17 19 17 18 13 15 12 15 18 5
12 14 12 19 16 15 15 20 6 15
Construct a grouped frequency distribution table with class length 5, taking the first interval 0 - 5 (5 not included). What main feature do we observe from this tabular representation ?

Answer 1

Step-by-step explanation:

To construct a grouped frequency distribution table with class length 5, taking the first interval 0 - 5 (5 not included).

of the given data

6 4 15 20 25 10 14 8 12 3

19 10 12 17 18 15 32 18 16 6

17 19 17 18 13 15 12 15 18 5 12 14 12 19 16 15 15 20 6 15

for example: 0-5 class includes 3,4

5-10 class includes 5,6,6,6,8

Table :

$</p><p>\begin{tabular}{|l|l|}\cline{1-2}</p><p>Class Interval & Frequency \\ \cline{1-2}</p><p>0-5 & 2 \\ \cline{1-2}</p><p>5-10 & 5 \\ \cline{1-2}</p><p>10-15 & 10 \\ \cline{1-2}</p><p>15-20 & 19 \\ \cline{1-2}</p><p>20-25 & 2 \\ \cline{1-2}</p><p>25-30 & 1 \\ \cline{1-2}</p><p>30-35 & 1 \\ \cline{1-2}</p><p>Total & 40 \\ \cline{1-2}</p><p>\end{tabular}</p><p>\end{table}$
