After defining the variables involved in a study, scientists have to identify individuals to study. The population is the group of individuals to whom we hope our conclusions will apply. Researchers generally hope that their conclusions will apply to a large population, such as all 20-year-olds in the country. Because it is not practical to examine everyone in the population, researchers study a
sample of people and assume that the results for the sample apply to the whole population. Briefly define the following types of samples: convenience sample, representative sample, random sample, and cross-cultural sample.
What will be an ideal response?
Convenience Sample: a group chosen because of its ease of study. An example is the use of college students taking a psychology course.
Representative Sample: closely resembles the population in its percentage of males and females, Blacks and Whites, young and old, or other characteristics that are likely to affect the results.
Random Sample: every individual in the population has an equal chance of being selected. For example, the researcher might take the census report for a state and try to contact 100 people
