Q2. The distance (in km) of 40 engineers from their residence to their place of work were found as follows:
5 3 10 20 25 11 13 7 12 31 19 10 12 17 18 11 32 17 16 2 7 9 7 8 3 5 12 15 18 3 12 14 2 9 6 15 15 7 6 12
Construct a grouped frequency distribution table with class size 5 for the data given above taking the first interval as 0-5 (5 not included). What main features do you observe from this tabular representation?
The record distances between the engineer's workplace and place of residence can be assembled as:
S.no. | Distances Intervals | Frequency | |
1 | 0-5 | 5 | |
5-10 | 11 | ||
3 | 10-15 | 11 | |
4 | 15-20 | 10 | |
5 | 20-25 | 1 | |
6 | 25-30 | 1 | |
7 | 30-35 | 1 | |
8 | TOTAL | 40 |
