Research Methodology & Design Flashcards

What is the primary purpose of research methodology?

Answer: To design and organize the research process.

Research methodology refers to the systematic plan and procedures used to conduct a study. Its primary purpose is to provide a structured framework for how the research will be carried out, from defining the problem to data collection and analysis. This ensures the research is organized, rigorous, and capable of yielding valid and reliable results.

Which of the following is an example of quantitative research?

Answer: Using surveys to collect numerical data.

Quantitative research focuses on collecting and analyzing numerical data to identify patterns, test relationships, and generalize findings to larger populations. Using surveys to collect numerical data, such as ratings, frequencies, or demographic figures, directly aligns with this approach. This allows for statistical analysis and objective measurement.

What is the key characteristic of qualitative research?

Answer: It aims to understand meanings, experiences, and concepts.

Qualitative research is characterized by its exploratory nature, aiming to delve deeply into complex phenomena. It seeks to understand the 'why' and 'how' behind human behavior, experiences, and perceptions. This approach uses non-numerical data like interviews and observations to uncover rich, descriptive insights and meanings.

What is a hypothesis in research?

Answer: A testable prediction about variables.

A hypothesis is a specific, testable statement or prediction about the relationship between two or more variables. It serves as an educated guess that researchers aim to prove or disprove through their study. This prediction guides the research design and data collection process.

What does 'sampling' refer to in research?

Answer: Choosing participants to represent the larger population.

Sampling in research involves selecting a subset of individuals or items from a larger population to participate in a study. The goal is for this chosen sample to accurately represent the characteristics of the entire population. This allows researchers to draw conclusions about the larger group without having to study every single member.

What is a literature review?

Answer: An analysis of previous research on the topic.

A literature review is a comprehensive survey of scholarly articles, books, and other sources relevant to a particular area of research. Its purpose is to identify what has already been studied, understand existing theories, and pinpoint gaps in current knowledge. This foundational step helps contextualize the new research and inform its design.

Why is data analysis important in research?

Answer: It provides a method for testing the hypothesis.

Data analysis is crucial because it allows researchers to systematically examine and interpret the collected data. By applying appropriate statistical or thematic methods, researchers can identify patterns, relationships, and trends within the data. This process is essential for testing the initial hypothesis and drawing meaningful conclusions from the study.

What is the significance of the findings in research?

Answer: They offer new knowledge and guide future research.

The significance of research findings lies in their ability to contribute new knowledge to a field and inform future inquiry. While findings may support or refute a hypothesis, their broader importance comes from expanding our understanding, challenging existing theories, or suggesting new directions for further research. They rarely provide 'conclusive evidence' but rather build upon the existing body of knowledge.

What is the purpose of a control group in an experiment?

Answer: To provide a baseline for comparison.

In an experiment, a control group is a group of participants who do not receive the treatment or intervention being studied. Its purpose is to provide a baseline for comparison against the experimental group, which does receive the treatment. This allows researchers to isolate the effect of the independent variable and determine if the intervention caused any observed changes.
