Research Design - PR2 Quiz

What is the main purpose of a research design?

• To conduct experiments on variables

• To outline the strategy for structuring a study logically

• To collect data on existing literature

• To create hypotheses for a study

Answer explanation

The main purpose of a research design is to outline the strategy for structuring a study logically. It provides a framework for collecting and analyzing data, ensuring the research is coherent and systematic.

Which type of research design is often used when limited prior studies exist on a topic?

• Causal

• Descriptive

• Exploratory

• Experimental

Answer explanation

Exploratory research design is used when there is limited prior research on a topic. It helps to gather initial insights and understand the problem better, making it ideal for new or under-researched areas.

What type of data collection method is commonly used in survey research design?

• Case analysis

• Laboratory experiments

• Questionnaires and interviews

• Focus group discussions

Answer explanation

In survey research design, data is typically collected using questionnaires and interviews, which allow researchers to gather responses directly from participants, making this method the most common for obtaining survey data.

In a correlational study, what is the primary objective?

• To prove causation between two variables

• To explore background information on a topic

• To determine the relationship between variables

• To describe a situation comprehensively

Answer explanation

In a correlational study, the primary objective is to determine the relationship between variables. This means identifying how changes in one variable may relate to changes in another, without implying causation.

Which type of evaluation is conducted after the implementation of a program to assess its outcomes?

• Formative Evaluation

• Summative Evaluation

• Process Evaluation

• Implementation Evaluation

Answer explanation

Summative Evaluation is conducted after a program's implementation to assess its overall outcomes and effectiveness, distinguishing it from formative evaluations, which occur during the program's development.

Why is choosing the correct research design important in a study?

• It ensures that data collection is easy

• It helps in addressing the research problem effectively

• It eliminates the need for data analysis

• It speeds up the publication process

Answer explanation

Choosing the correct research design is crucial as it directly impacts how effectively the research problem is addressed, ensuring that the study yields valid and reliable results.

Which design is suitable for determining the 'who, what, when, where, and how' of a topic?

• Exploratory

• Descriptive

• Causal

• Evaluative

Answer explanation

The descriptive design is ideal for answering the 'who, what, when, where, and how' of a topic, as it focuses on providing a detailed account and understanding of the subject matter.

If a study examines the impact of remedial math classes on student performance, what type of evaluation is this?

• Needs Assessment

• Process Evaluation

• Outcome Evaluation

• Implementation Evaluation

Answer explanation

This study evaluates the effects of remedial math classes on student performance, focusing on the results or outcomes of the intervention, which classifies it as an Outcome Evaluation.

In research design, what does a formative evaluation focus on?

• The effectiveness of a program after completion

• Understanding initial program needs

• Examining program quality during implementation

• Comparing costs and benefits of the program

Answer explanation

A formative evaluation focuses on examining program quality during implementation, allowing for adjustments and improvements based on ongoing feedback, rather than assessing effectiveness after completion.

A research project aims to assess the initial needs for a program. Which type of evaluation is this?

• Needs Assessment

• Process Evaluation

• Summative Evaluation

• Impact Evaluation

Answer explanation

A Needs Assessment evaluates the initial requirements for a program, making it the correct choice for assessing initial needs. Other evaluations focus on processes, outcomes, or impacts after implementation.
