A systematic investigation which involves collecting, analyzing, and interpreting information in a sequential manner in order to increase our understanding of the phenomenon of interest is also known as

• Statistics

• Analysis

• Research

• Methodology

When a researcher wants to study a counseling intervention with individuals who live at a homeless shelter versus individuals who live at a domestic violence shelter, the best research design would be

• Experimental design

• Predictive design

• Case study

• Quasi-experimental design

When a researcher is interested in linking or making an association between two or more phenomena, the design that should be used is

• Descriptive

• Exploratory

• Correlational

• Grounded theory

Researchers wishing to study categorical variables would use which research design?

• Narrative

• Phenomenological

• Qualitative

• Quantitative

What is the key difference between a quasi-experiment and a "true experiment?"

• Quasi experiments do not have controlled variables.
• Quasi experiments take place in naturalistic environments; true experiments take place in laboratories
• In a quasi experiment, participants have a trait that determines which condition they are in; in a true experiment, they are randomly allocated.
• Quasi experiments are cross-sectional; true experiments are longitudinal (take place over a long period of time).

What research method is used by researchers who study single individuals in depth, in order to uncover general principles of thinking and behavior?

• experimentation

• correlational study

• naturalistic observation

• case study

What research strategy is used by a company who sends a satisfaction questionnaire to its current customers at the end of the year.

• observation

• content analysis

• survey

• experiment

Quantitative research

• Is an open approach to social phenomena

• Employs predetermined instruments to measure and observe

• Reports data in narrative form

• Is only experimental in nature

A researcher wants to test a specific hypothesis and applies random assignment for the study. Which quantitative research method should be used for this study?

• experimental

• correlational

• causal-comparitive

• grounded theory

It is done to check the correctness and verify the findings of the study.

• Large Sample Sizes

• Numerical Data

• Replication

• Objective
