  2. 2. Sakuma India An fmcg company. Product discussed-digital camera. 42% market share in still camera market. Their new launched series of cyber shot, 50,000 cameras are already sold. Now in order to get the feedback from the users…here are various methods given by their employees. Questionnaire survey through email, postal mail or telephonic interview. Finally the telephonic survey is decided and only 10-20% customer should be contacted.
  3. 3. Now the question arises that howshould they contact??? Active company’s blog users. Random sampling Choosing every nth customer. Random groups according to zones, states and metropolitan cities. Group customers on the basis of camera model they have buy.
  4. 4. To select a proportionate cluster sample of 5000members of the total 50,000 consumers belonging toeach zone i.e. North, South, East & WestSo lets assume that the consumers are divided in this strata or sub-group in 4 different zones….. north = 15000 south = 13000 east = 12000 west = 10000
  5. 5. Now lets calculate the overall samplingfunction in the following manner. f = n/N = 5000/50,000 = .1 where n = sample size & N = population size
