Understanding Quantitative Research

The video tutorial covers the characteristics, strengths, weaknesses, and types of quantitative research. It clarifies what research is not, emphasizing that research is a systematic process involving data collection, analysis, and interpretation. The tutorial compares qualitative and quantitative research, highlighting their differences and uses. It also discusses the strengths and weaknesses of quantitative research, such as its objectivity and large sample size requirements. Finally, it explains various research designs, including non-experimental, quasi-experimental, and experimental approaches.

What is one of the main characteristics of quantitative research?

• It is primarily exploratory.

• It relies on subjective data.

• It uses numerical data for analysis.

• It focuses on small sample sizes.

Which of the following is NOT considered research?

• Gathering information from libraries.

• Transporting facts without analysis.

• Systematically analyzing data.

• Interpreting collected data.

What does the iterative nature of research imply?

• Researchers may revisit steps multiple times.

• Research always supports the initial hypothesis.

• Research is a one-time process.

• Research steps are fixed and linear.

How does qualitative research differ from quantitative research?

• It uses numerical data.

• It is conclusive in nature.

• It focuses on words and meanings.

• It requires large sample sizes.

What is a key feature of mixed-method research?

• It disregards statistical tools.

• It focuses solely on numerical analysis.

• It combines both qualitative and quantitative data.

• It only uses qualitative data.

Which type of research design involves no experimental manipulation?

• Causal-comparative

• Experimental

• Quasi-experimental

• Non-experimental

What is the primary goal of correlational research?

• To identify relationships between variables.

• To manipulate independent variables.

• To establish cause and effect.

• To test hypotheses.

In which research design is the independent variable not manipulated?

• Descriptive

• Experimental

• Quasi-experimental

• Non-experimental

What is a characteristic of a quasi-experimental design?

• Manipulation of all variables.

• Random selection of participants.

• Use of naturally occurring groups.

• Complete control over all variables.

What is the purpose of replication in quantitative research?

• To duplicate previous studies.

• To validate and confirm results.

• To simplify the research process.

• To explore new hypotheses.
