Distance (in km) of 40 engineers from their place of residence to their place of work were found as follows:



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?

Answer 1

From the above table we observe that out of 40 female engineers 36 (5 +11 + 11 + 9) engineers i.e.. 90% of the total female engineers reside less than 20 km from their place of work.

Question ⤵

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?

Answer ⬇

From the above table we observe that:

(i) Frequencies of class interval 5 – 10 and 10 – 15 are equal, i.e. 11 each. It shows that maximum number of engineers have their residences at 5 to 15 km away from their work place.

(ii) Frequencies of class intervals 25 – 30 and 25 – 30 are also equal, i.e. 1 each. It shows that minimum number of engineers have their residences at 20 to 30 km away from their work place.
