Perbedaan Penelitian Kuantitatif dan Kualitatif

Summary

In this video, the speaker discusses the differences between quantitative and qualitative research methods. He explains that quantitative research focuses on numerical data and uses systematic, objective methods like surveys and statistical analysis. In contrast, qualitative research deals with descriptive data, evolving research problems, and flexible sampling methods. The speaker highlights key distinctions in theory, data collection, and analysis techniques, sharing personal experiences in both research methods. The video concludes with a call for viewer feedback on future topics and support for the channel.

Takeaways

• 😀 Research is about searching for facts and theories to prove or disprove them, and it should be conducted systematically and objectively.
• 😀 A research method should be systematic, meaning it can be repeated by others, with clear steps outlined.
• 😀 Objectivity in research means that findings should not be influenced by external pressures, such as government or institutional bias.
• 😀 Quantitative research focuses on data that can be measured numerically, while qualitative research involves non-numeric data, such as text and narratives.
• 😀 The title of quantitative research is specific and remains mostly unchanged, while qualitative research titles may change as new findings emerge during the study.
• 😀 In quantitative research, the problem is fixed and follows predefined hypotheses, while in qualitative research, the problem may evolve based on new data from informants.
• 😀 Quantitative research relies heavily on theories and literature, whereas in qualitative research, the theory is temporary and evolves as the study progresses.
• 😀 Quantitative research uses a population and sample, while qualitative research does not use defined samples or populations. It instead focuses on data saturation.
• 😀 Quantitative research generally uses probability sampling (random sampling), while qualitative research uses purposive sampling, selecting participants based on their relevance to the study.
• 😀 Data collection in quantitative research uses instruments like surveys and questionnaires, while in qualitative research, tools like interviews, recorders, and field notes are used.
• 😀 In quantitative research, data analysis is done using statistical methods, while qualitative research involves continuous analysis of data as it is collected, without using statistical techniques.

Q & A

What is the main topic of the video?

The main topic of the video is the comparison between quantitative and qualitative research, specifically discussing their differences and characteristics.

What is the definition of 'research' as mentioned in the video?

Research, as explained in the video, is derived from the word 're-search', meaning to search again for facts and theories, with the goal of proving or disproving existing theories and obtaining new findings.

What are the two key requirements of a research method?

The two key requirements of a research method are being systematic and objective. A research method must be structured so others can replicate it, and it must not be influenced by external factors or biases.

What is the key difference between quantitative and qualitative research in terms of data?

Quantitative research involves collecting numerical data, while qualitative research involves gathering descriptive data, often in the form of text or narratives.

How are research titles different in quantitative and qualitative studies?

In quantitative research, the title is specific and stable, as it is based on established theories. In qualitative research, the title often changes, reflecting new insights gathered from the field during the study.

How does the formulation of research problems differ between quantitative and qualitative research?

In quantitative research, the research problem is clear and stable, based on existing theories. In qualitative research, the research problem evolves based on the findings and insights obtained during the research process.

What is the role of theory in quantitative and qualitative research?

In quantitative research, theory serves as a foundation for creating hypotheses and defining variables. In qualitative research, theory is considered provisional and may change as new data and insights are gathered.

What is the difference in population and sampling between quantitative and qualitative research?

Quantitative research works with populations and samples, where a sample is selected from a larger population. In contrast, qualitative research doesn't focus on populations or samples; instead, it collects data until saturation is reached, meaning no new information is emerging.

What type of sampling method is used in quantitative and qualitative research?

Quantitative research typically uses probability sampling, where every individual in the population has an equal chance of being selected. Qualitative research, on the other hand, often uses purposive sampling, where participants are chosen based on specific criteria or experience.

How is data analysis conducted in quantitative and qualitative research?

In quantitative research, data analysis is conducted using statistical methods after the data is collected. In qualitative research, data analysis is ongoing, with researchers analyzing data as it is collected, without relying on statistical methods.
