Types of Quantitative Research

What is the main purpose of experimental research?

• To describe the characteristics of a population

• To establish a causal relationship

• To test for relationships between variables

• To manipulate dependent variables

Which feature is essential in true experimental research?

• Random assignment of groups

• Lack of control groups

• Non-manipulated independent variables

• Systematic description of phenomena

What is the primary difference between quasi-experimental and true experimental research?

• True experimental lacks control groups

• Quasi-experimental uses random assignment

• Quasi-experimental does not manipulate the independent variable

• True experimental focuses only on descriptive statistics

Descriptive research primarily aims to answer which question?

• "Why does this happen?"

• "What is happening?"

• "How does this occur?"

• "What are the effects?"

Which of the following is not a type of quantitative research?

• Experimental

• Descriptive

• Ethnographic

• Correlational

What characteristic defines descriptive research?

• Random assignment of participants

• Manipulation of variables

• Systematic information about a phenomenon

• Testing relationships between two variables

What is the key focus of correlational research?

• To establish causation

• To describe population characteristics

• To test relationships between variables

• To manipulate independent variables

Which of the following best defines quasi-experimental research?

• It uses random group assignment

• It aims to establish cause and effect without manipulation

• It focuses on testing for variable relationships

• It provides detailed descriptions of phenomena

What is a critical criterion for true experimental research?

• Inclusion of only one group

• Systematic observation

• Presence of both experimental and control groups

• Testing non-manipulated variables

In correlational research, what is primarily tested?

• Systematic manipulation of a variable

• Cause-and-effect relationships

• The relationship between two variables

• The randomness of sample selection
