Professor Alsmith looks at changes in self-esteem across adolescence by measuring the self-esteem of 11 year olds, 13 year olds,
15 year olds, and 17 year olds and comparing the results between the groups. This is an example of a(n) _________.a. correlational study b. cross-sectional study
c. archival study
d. longitudinal study
A. Correlational study is a research design in which a researcher seeks to find out if two or more variables are related and if so, then in what way. An example is difference in people's height,
B. Cross-sectional study is a type of study that involves observing a population or representative subset at a particular point in time and analysing the data. An example is evaluating people from different ages.
C. Archival study involves seeking out and retrieving evidence from archival records.
D. Longitudinal study involves gathering data from observing the same individuals repeatedly over a period of time.
It's based on opinion, but I would put that they won't start and get an addiction at an early age so it will be more difficult for them to start later in life.
