Research Design Concepts and Methods

The video tutorial by Aisha on Educational Hub covers the concept of research design, its purpose, types, and methods. It explains the differences between fixed and flexible designs, and how to create a research design. The video also distinguishes between research design and approach, and outlines the characteristics of a good research design. Additionally, it discusses qualitative and quantitative research methods, and the key differences between them.

What is the primary purpose of a research design?

• To ensure all variables are independent

• To collect data randomly

• To provide a structured plan for a study

• To eliminate the need for a hypothesis

Which type of research design aims to describe a population or phenomenon?

• Explanatory research

• Descriptive research

• Evaluation research

• Exploratory research

What is the main focus of explanatory research?

• To evaluate a program's effectiveness

• To explain why something happens

• To describe what is happening

• To explore new areas

Which research design is known for assessing the value of resources in a project?

• Descriptive research

• Explanatory research

• Exploratory research

• Evaluation research

What distinguishes a quasi-experimental design from a true experimental design?

• It is only qualitative

• It always requires a hypothesis

• It does not use random sampling

• It uses random sampling

In a fixed research design, what is typically predetermined?

• The sample size

• The data collection methods

• The sequence of the study

• The outcome of the study

What is the first step in creating a research design?

• Analyzing data

• Choosing data collection methods

• Developing a hypothesis

• Identifying learning outcomes

How does a research design differ from a research approach?

• Design is the framework, approach is the tools and techniques

• Design is about data collection, approach is about analysis

• Design is qualitative, approach is quantitative

• Design is flexible, approach is fixed

What is a key characteristic of a good research design?

• It should be error-prone

• It should minimize bias

• It should be inflexible

• It should be expensive

What is a research method?

• A random plan for data collection

• A hypothesis for the study

• A conclusion of the research

• A logical plan for conducting research
