Q & A

What is the main focus of the video lesson?

The main focus of the video lesson is to introduce quantitative research, define it, and describe its characteristics.

What does quantitative research involve?

Quantitative research involves the use of computational procedures in an objective, methodical, and experiential investigation of phenomena, with an emphasis on numerical analysis of data that can be generalized to a larger population.

What is the primary concern of quantitative research?

The primary concern of quantitative research is the number and its relationship with events, statistics, and probability.

How does quantitative research approach hypothesis testing?

Quantitative research approaches hypothesis testing by using statistical techniques to analyze data, such as examining the relationship of variables in a scatter diagram or different types of correlation.

What are the 8 characteristics of quantitative research mentioned in the script?

The 8 characteristics are: 1) Objective, not subjective; 2) Clearly defined research questions; 3) Clearly structured research instruments; 4) Numerical presentation of data; 5) Large sample size; 6) Replicated but not duplicated; 7) Data can be used to predict future outcomes; 8) Data can be used to verify existing facts and develop new concepts.

Why is precision and accuracy of measurement important in quantitative research?

Precision and accuracy of measurement are important in quantitative research to ensure reliable and valid results, and to avoid biases in the conclusions drawn from the data.

How should research questions be formulated in quantitative research?

Research questions in quantitative research should be precise and clear, allowing the readers and researchers to understand the objectives and what the researcher is looking for. They should include identification of respondents, interventions, comparison variables, and outcomes.

What does the script imply about the organization of research instruments in quantitative research?

The script implies that research instruments in quantitative research should be well-organized and planned, with different dimensions and scales, enabling the collection of measurable characteristics of the population.

Why is a large sample size important in quantitative research?

A large sample size is important in quantitative research to increase the reliability of data analysis, avoid biases, and ensure that the results are representative of the population being studied.

How can quantitative research be used to predict future outcomes?

Quantitative research can use complex mathematical calculations and computer-aided modeling to predict future outcomes based on past data. This is particularly useful when past numerical data is available and patterns are expected to continue into the future.

What is the role of replication in quantitative research?

Replication in quantitative research is important to verify or confirm the correctness of the results in different settings, ensuring the validity of the findings and eliminating the possibility of spurious conclusions.

How can quantitative research contribute to the development of new concepts?

Quantitative research can contribute to the development of new concepts by providing empirical evidence that supports or challenges existing theories, and by offering insights that can lead to innovative ideas for practical applications.
