Research Methods and Designs

Types of Research

• Qualitative Research: Explores attitudes, opinions, and behaviors through non-numerical data collection and analysis.
• Quantitative Research: Focuses on numerical data collection and statistical analysis to identify patterns and trends.
• Mixed Methods Research: Combines both qualitative and quantitative approaches to provide a comprehensive understanding.

Research Designs

• Experimental Design: Involves manipulating one or more variables to observe their effect on a dependent variable.
• Quasi-Experimental Design: Lacks random assignment of participants to groups, but still attempts to establish cause-and-effect relationships.
• Survey Research: Involves collecting data through self-reported measures, such as questionnaires or interviews.
• Case Study Research: In-depth examination of a single case or a small number of cases to gain detailed insights.

Research Participants

• Sampling: Selecting a subset of participants from a larger population to represent the whole.
• Population: The entire group of individuals or data points that the research aims to understand or describe.
• Sample Size: The number of participants selected for the study, which can impact the accuracy and reliability of results.

Research Ethics

• Informed Consent: Obtaining participants' voluntary agreement to participate in the study after being fully informed of the risks and benefits.
• Anonymity: Protecting participants' identities and ensuring confidentiality of their data.
• Debriefing: Providing participants with information about the study's purpose and results after completion.

Research Process

• Literature Review: Critical analysis of existing research to identify gaps and inform the study's objectives and methods.
• Data Collection: Gathering data through various methods, such as surveys, experiments, or observations.
• Data Analysis: Examining and interpreting the collected data to draw conclusions and answer research questions.
• Results and Discussion: Presenting the findings and implications of the study, as well as limitations and potential avenues for future research.

Types of Research

• Qualitative Research explores attitudes, opinions, and behaviors through non-numerical data collection and analysis, providing insights into people's thoughts and feelings.
• Quantitative Research focuses on numerical data collection and statistical analysis to identify patterns and trends, often used to quantify and generalize findings.
• Mixed Methods Research combines both qualitative and quantitative approaches to provide a comprehensive understanding of the research topic.

Research Designs

• Experimental Design involves manipulating one or more variables to observe their effect on a dependent variable, allowing for causal inferences to be made.
• Quasi-Experimental Design lacks random assignment of participants to groups, but still attempts to establish cause-and-effect relationships, often used in real-world settings.
• Survey Research involves collecting data through self-reported measures, such as questionnaires or interviews, to understand people's attitudes, opinions, and behaviors.
• Case Study Research provides an in-depth examination of a single case or a small number of cases to gain detailed insights into complex phenomena.

Research Participants

• Sampling involves selecting a subset of participants from a larger population to represent the whole, with various sampling techniques available, such as random, stratified, or convenience sampling.
• Population refers to the entire group of individuals or data points that the research aims to understand or describe.
• Sample Size has a significant impact on the accuracy and reliability of results, with larger sample sizes generally providing more reliable results.

Research Ethics

• Informed Consent involves obtaining participants' voluntary agreement to participate in the study after being fully informed of the risks and benefits, ensuring their autonomy and protection.
• Anonymity protects participants' identities and ensures confidentiality of their data, promoting trust and reducing potential harm.
• Debriefing provides participants with information about the study's purpose and results after completion, helping to build trust and ensure transparency.

Research Process

• Literature Review involves a critical analysis of existing research to identify gaps and inform the study's objectives and methods, providing a solid foundation for the research.
• Data Collection involves gathering data through various methods, such as surveys, experiments, or observations, depending on the research question and design.
• Data Analysis examines and interprets the collected data to draw conclusions and answer research questions, often using statistical techniques and software.
• Results and Discussion present the findings and implications of the study, as well as limitations and potential avenues for future research, providing a comprehensive overview of the study's outcomes.
