Answer:
Olivia is conducting a longitudinal study on adolescence. During the first wave she interviewed each participant about their familial relationships. She used the information she obtained to develop a measure of familial relationships that she administered during the second wave of the study. In the first wave, Olivia used qualitative research, in the second wave she used quantitative research.
Step-by-step explanation:
The qualitative research can be seen as a term that covers a series of methods and techniques with interpretive value that aims to describe, analyze, decode, translate and synthesize the meaning of facts that arise more or less naturally. It has a naturalistic interpretive approach towards its object of study, so it studies reality in its natural context, interpreting and analyzing the meaning of the phenomena according to the meanings it has for the people involved. Quantitative research is one in which quantitative data on variables are collected and analyzed. Its purpose is to find general laws that explain the nature of its object of study from observation, verification and experience. That is, from the analysis of experimental results that yield verifiable numerical or statistical representations.
