In a study of gang behavior, Jankowski (1991) purposefully included at least some participants from several different ethnic gan
gs, as well as large and small gangs, and gangs from different cities and regions of the country. This process of selecting at least some participants from different types of gangs represents what kind of sampling procedure?A. Simple random samplingB. Quota samplingC. Theoretical samplingD. Stratified samplingE. Snowball sampling
The type of sampling used in Jankowski's study of gangs is Option D. Stratified sampling.
Explanation:
With stratified sampling, the researcher will partition the population into different groups, usually based on some characteristic that is common to that group. In this case, it was the different kinds of gang membership. Then, the researcher will take a sample of people within each specific group using another sampling method like simple random sampling for instance. The groups that are used in stratified sampling are called strata. Another example would be a national survey that is divided into strata of the different major ethnic groups that comprise the national population.
In general, psychological health refers to mental health. It is more than just the absence of any illness. It refers to having healthy thoughts and feelings. It refers to the ability of a person to communicate with others in an effective manner and do not feel the urge to isolate himself from others. Psychological health refers to the social well being of a person. A person should realize that mental health is as important as physical health.
