Document Summary
Prof. brym 04/03/13: surveys are part of the fabric of everyday life in north america and elsewhere in the world, iq tests, sat"s are types of surveys we are therefore very familiar with them. People who are motivated to say nasty things about their children are the ones who are most likely to answer such a question! A sample is a part of a group. A voluntary response sample is a group of people who chose themselves in response to a general appeal. A representative sample is a group of people chosen so their characteristics closely match those of the population of interest (over-representation of elderly in malls) A convenience sample consists of people who are easiest to reach. If respondents are chosen at random and an individual"s chance of being chosen is known and greater than zero, the respondents constitute a probability sample (first you need a sampling frame)
