16. Compulsory Case study                                                 (1 x 20 = 20)

 

Mr. Mehta has a chain of restaurants in many cities of northern parts of 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 has already done a course in fashion designing and wanted  to do something different for the customers of this industry. An idea struck him that he should design garments for people who are very bulky but want a lean 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 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 the entrance of various malls and their job would be to look at people who walked into the mall and see whether the concerned person was wearing a big sized shirt or 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.

Questions:

• Name the sampling design that is being used in the study. Do you think it is a suitable method.

 

• What are the limitations of the design so chosen?

 

• Can you suggest a better design?

 

• What method of data collection is being employed? What other methods can be employed?
