Answer:
Exploratory sequential
Explanation:
The exploratory sequential design is a type of design that is used by researchers and it is characterized by:
- An initial qualitative phase of data collection.
- A phase of quantitative data collection
- A final phase of integration of data from the first two phases.
The purpose of this type of design is to gather the qualitative data to have a first understanding/approach to a phenomenon and then proceed to collect the quantitative data that will allow to explain the relationships found in the qualitative data.
In this example,<u> the researcher first conducts observations of juvenile gang members (qualitative phase of data collection) and later he asks these members to complete a survey about the types of delinquency they can engage in (quantitative phase). </u>With these two types of data, the researcher will be able to see the relationships between everyday lives of the gang members and the type of delinquency they engage in. Thus, this is an example of exploratory sequential design.
Personal control beliefs, also referred to as locus of control and personal mastery beliefs, reflect individuals' beliefs regarding the extent to which they are able to control or influence outcomes.
