Q & A

What is the main focus of the video lesson presented by Miss Jenny Vijay Arimbuyutan?

The main focus of the video lesson is to provide assistance in understanding the concepts of quantitative research and its application in various fields.

What are the basic elements of research that are essential for good research practices?

The basic elements of research essential for good research practices are not explicitly listed in the script, but the lesson emphasizes the importance of quantitative research across different fields.

How can quantitative research be used in the education sector?

Quantitative research can be used in education to measure the performance of students and teachers, assess the effectiveness of teaching methods and programs, and gauge the satisfaction of stakeholders including students, faculty, parents, administrators, and organizations.

What role does quantitative research play in business?

In business, quantitative research is a valued tool for improving marketing strategies, making informed decisions on product or service development, and soliciting consumer opinions for productivity.

How can communication researchers use quantitative research to study communication phenomena?

Communication researchers can use quantitative research to generalize understanding of specific communication phenomena to larger populations, such as studying the effects of disciplinary behavioral control statements in classrooms or communicative behaviors in romantic relationships.

What is the significance of random sampling in quantitative research within the field of demographics?

Random sampling in quantitative research within demographics is significant as it allows for the collection of representative samples from larger populations, helping to discover patterns, associations, correlations, and other features of the population.

How can quantitative research be applied in economics?

Quantitative research in economics can be used to evaluate economic behavior, design economic policies and techniques, and make more accurate and efficient research of complex economic phenomena and their interdependencies, with the aim of making predictions and forecasting future trends.

What example is given in the script about the application of quantitative research in sports medicine?

The script provides an example from the University of Eastern Finland, where a quantitative study investigated the relationship between the growth of fast-food chains and childhood obesity, as well as the intervention needed to prevent obesity from reaching serious proportions.

How can medical education benefit from experimental research designs?

Medical education can benefit from experimental research designs by enhancing the quality of education through testing interventions like curriculum, teaching-learning processes, or assessments, allowing researchers to overcome validity concerns and infer potential cause-and-effect generalizations.

What types of relationship questions are explored in behavioral science using quantitative research?

In behavioral science, quantitative research tends to explore how one behavior exhibited by people is related to other types of behavior, such as the relationship between verbally aggressive behaviors and physical aggression, or certain supervisor communication skills and the emotional experiences of employees.

What is the role of quantitative psychologists in studying human behavior and characteristics?

Quantitative psychologists study and develop methods and techniques used to measure human behavior and other characteristics, involving statistical and mathematical modeling of psychological processes, the design of research studies, and the analysis of psychological data.

How can quantitative research be used in political science to investigate phenomena?

In political science, quantitative research can be used to properly investigate phenomena by providing quantitative data that describes the circumstances best, such as studying political revolutions and the emergence of political theory.

What is the final task expected of the viewers at the end of the session?

The final task expected of the viewers is to identify different disciplines where quantitative research can be used, emphasize its contribution across fields, and illustrate its importance.
