Mr. Xhas a chain of restaurants in many cities in northern India and was interested in diversifying his business. His only son, Ramal, never wanted to be in the hospitality line. To settle Ramal into a line that would interest him, Mr. X decided to venture into garment manufacturing. He gave this idea to his son, who liked it very much. Ramal 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 Page 1 of 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 (42 sizes and above) and large-sized trousers (38 sizes and above). Ameeting was called of experts from the garment industry and a number of fashion designers to discuss how they should proceed. Acommon 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. Asuggestion that came up was that they should employ some observers at the entrances of various malls and their job would be to look at people who walked into the malls and see whether the concerned person was wearing big-sized shirt or trousers. 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.
