Understanding Research Designs

What is the main focus of experimental research designs?

• Testing theoretical models.

• Identifying trends in data.

• Establishing cause-and-effect relationships.

• Measuring participant satisfaction.

What are the two main groups in an experimental design?

• Experimental group and Control group

• Primary group and Secondary group

• Variable group and Static group

• Test group and Sample group

What is the purpose of a pre-test in experimental research?

• To randomly assign participants to different treatment groups.

• To collect qualitative data about participants' experiences.

• To determine the effectiveness of the treatment immediately after it is applied.

• The purpose of a pre-test in experimental research is to establish a baseline measurement for comparison after the treatment.

How does a post-test differ from a pre-test?

• A post-test is given before the learning process starts.

• A pre-test evaluates learning outcomes while a post-test assesses prior knowledge.

• A pre-test assesses prior knowledge; a post-test evaluates learning outcomes.

• A pre-test measures the same knowledge as a post-test.

What is a true experimental design characterized by?

• Use of a single group without random assignment.

• Manipulation of an independent variable and random assignment of participants.

• Manipulation of multiple variables without control groups.

• Observation of a dependent variable only.

What does quasi-experimental design imply?

• An experimental design that includes random assignment of participants.

• A research method that resembles experimental design but lacks random assignment.

• A method that only uses qualitative data without any control groups.

• A research method that focuses solely on observational studies without any manipulation.

Why is random selection important in true experimental design?

• Random selection ensures representativeness and minimizes bias in experimental groups.

• Random selection guarantees that all variables are controlled.

• Random selection is only necessary for qualitative research.

• Random selection increases the size of the sample.

What type of relationships is true experimental design best for examining?

• Causal relationships

• Exploratory relationships

• Descriptive relationships

• Correlational relationships

Can a control group receive treatment in an experimental design?

• Control groups are optional in experimental designs.

• Yes, a control group can receive a placebo treatment.

• A control group receives the same treatment as the experimental group.

• No, a control group does not receive the treatment being tested.

What is the significance of manipulating variables in experimental research?

• It simplifies the research process.

• It reduces the need for control groups.

• It enables the establishment of cause-and-effect relationships.

• It helps in collecting qualitative data.
