Q.5
CASE STUDY:
Mr Mohan Mehata has a chain of restaurants in many cities of
northern India and was interested in diversifying his business. His
only son, Kamal, never wanted to be in the hospitality line. To settle
Kamal into a line, which would interest him? Mr. Mehta decided to
venture into garment manufacturing. He gave this idea to his son,
who liked it very much. Kamal had already done a course in fashion
designing and wanted to do something different for the consumers of
this industry. An idea struck him that he should design garments for
people who are very bulky but want a lean back look after wearing
readymade garments. The first thing that came to his mind was to
have an estimate of people who wore large sized shirts (40 size and
above) and large sized trousers (38 size and above).
A meeting was called of experts from the garment industry and a
number of fashion designers to discuss on how they should proceed.
A common concern for many of them was to know the size of such a
market. Another issue that was bothering them was how to approach
the respondents. It was believed that asking people about the size of
their shirt or trouser may put them off and there may not be any
worthwhile response. A suggestion that came up was that they should
employ some observers at entrances of various malls and their job
would be look at people who walked into the malls and see whether
the concerned person was wearing a big sized shirt of trouser. This
would be a better way of approaching the respondents. This
procedure would help them to estimate in a very simple way the
proportion of people who wore big sized garments.
Name the sampling design that is being used in the study.
