the researcher divides the entire population into different subgroups or strata‚ then randomly selects the final subjects proportionally from the different strata” (Sincero‚ 2012). In surveys‚ the sampling frame is the list of cases from which the sample is selected. Easily obtained sampling frames would include telephone directories and lists of electors. These have obvious problems in terms of non-representativeness -for example‚ telephone directories only list people with telephones who are responsible

Research proposal Executive summary: The research project proposed will consist of an analytical review of fast food with particular reference to India. Some researchers blame the increased consumption of ‘big brand’ fast foods (such as McDonald’s) for expanding waistlines. Nutritional profiling in the initial study showed that the energy provided in a typical fast food meal seemed ‘appropriate’ in terms of a general daily intake but that increased meal sizes‚ poor ordering decisions and choice

PRINCIPLES of SAMPLING 1. Appraisals that involve sampling are estimates and predictions only. 2. Estimations based on proportionately large samples and on representative samples are accurate. 3. Sampling may be temporal or categorical. Categorical- if the sample is taken proportionally from categories for group Temporal- when the sample is in terms of time. Disadvantages of Sampling * If sampling is biased‚ or not representative‚ the conclusion may not be valid or reliable.

Quality Assurance Sampling has been used to draw the sample from the entire population of the catchment area of the Child Development programme implemented by the NGO partner. The NGO is working in 4 clusters consisting 27 small villages with a total population of 2721 House holds spread in small colonies. All the 27 villages have been converted in to 7 supervisory areas for the purpose of the study and for future supportive supervision. The sample size has been taken as 19 for each supervisory area

difference between a probability sample and a nonprobability sample. The difference between nonprobability and probability sampling is that nonprobability sampling does not involve random selection and probability sampling does. Does that mean that nonprobability samples aren ’t representative of the population? Not necessarily. But it does mean that nonprobability samples cannot depend upon the rationale of probability theory. At least with a probabilistic sample‚ we know the odds or probability
