QUIZ NO. 3 PR 2 QUANTITATIVE RESEARCH TYPES

How does descriptive research differ from other types of research?

• Descriptive research differs by focusing on observation and description without manipulation of variables, unlike experimental or correlational research.

• Descriptive research requires a large sample size to be valid.

• Descriptive research is primarily focused on statistical analysis and hypothesis testing.

• Descriptive research involves manipulating variables to establish cause and effect.

What is a key characteristic of cross-sectional research?

• It focuses on cause-and-effect relationships.

• It involves multiple groups being studied simultaneously.

• It collects data over a long period of time.

• It captures data at one specific point in time.

In quasi-experimental research, what is typically lacking compared to true experiments?

• Control over extraneous variables.

• Random assignment of participants to groups.

• Longitudinal data collection.

• Use of a placebo group.

What is the main purpose of single subject experimental research?

• To assess group behavior in a large population.

• To determine the average effect of an intervention across multiple subjects.

• To compare different interventions on a single subject.

• To evaluate the effects of an intervention on an individual subject.

How does pre-experimental research differ from true experimental research?

• True experimental research is always conducted in a laboratory setting, while pre-experimental research is not.

• Pre-experimental research involves random assignment, while true experimental research does not.

• Pre-experimental research does not use random assignment or control groups, while true experimental research does.

• Pre-experimental research uses control groups, while true experimental research does not.

What does ex post facto research investigate?

• Ex post facto research investigates the effects of past events on current conditions.

• Ex post facto research studies future predictions based on current data.

• Ex post facto research focuses on experimental designs to test hypotheses.

• Ex post facto research analyzes the effectiveness of current policies.

Which type of research is often used to identify relationships between variables?

• Qualitative research

• Correlational research

• Descriptive research

• Experimental research

What is a common method used in descriptive research?

• Interviews

• Focus groups

• Case studies

• Surveys

In causal comparative research, what is the independent variable?

• The independent variable is always a constant.

• The independent variable is the outcome of the study.

• The independent variable is the one that is measured.

• The independent variable is the variable that is manipulated or categorized.

What type of data is primarily collected in cross-sectional research?

• Only qualitative data from multiple time points.

• Quantitative and qualitative data at a single point in time.

• Quantitative data collected over several years.

• Qualitative data from a single participant.
