What is the scientific method as described in the Wallace Wheel?
The scientific method outlines a systematic approach to research and inquiry.
Define hypothesis in the context of the scientific method.
A specific, testable prediction about relationships between variables
Hypotheses are essential for guiding research and experimentation.
What are the two main approaches to the scientific method?
These approaches differ in their starting points and methodologies.
In the deductive approach, what is the order of steps?
This approach is common in quantitative research.
What is the focus of qualitative research?
Qualitative research seeks to understand deeper meanings and patterns.
What is the difference between basic and applied research?
Basic research is knowledge-driven, while applied research focuses on practical problem-solving.
What are the four purposes of research?
Each purpose serves a different aspect of understanding and utilizing research findings.
List the steps in the research process using the deductive approach.
These steps guide researchers from question formulation to application of findings.
What are the key elements of research ethics?
Ethical considerations are crucial to protect participants in research.
True or false: Informed consent means participants must fully understand the research before agreeing to participate.
TRUE
Informed consent is a fundamental ethical requirement in research.
What is the difference between anonymity and confidentiality in research?
Both concepts are essential for protecting participant privacy.
What is the role of Institutional Review Boards (IRBs)?
Evaluate research proposals to protect human participants
IRBs ensure ethical compliance and minimize risk in research.
Define independent variable (IV).
Cause, predictor
The independent variable is manipulated to observe its effect on the dependent variable.
Define dependent variable (DV).
Effect, outcome
The dependent variable is measured to assess the impact of the independent variable.
What are the three conditions required for causation?
These conditions must be met to establish a causal relationship.
What is the classical experiment known for?
The strongest research design for establishing causation
It involves random assignment, pretesting, and posttesting.
What is the purpose of operationalization in research?
Turn abstract concepts into measurable variables
Operationalization is crucial for effective data collection and analysis.
List the levels of measurement.
Each level has different properties and implications for data analysis.
What does reliability in measurement refer to?
Consistency of results
Reliable measurements yield the same results under consistent conditions.
What does validity in measurement refer to?
Accuracy of measurement
Valid measurements accurately reflect the concept being studied.
What is the Crime Severity Index (CSI)?
Measures police-reported crime in Canada by accounting for both how many crimes occur and how serious they are
The CSI provides a more nuanced understanding of crime trends.
Define population in research.
The entire group that you want to draw conclusions about
Understanding the population is essential for effective sampling.
What is sampling bias?
Occurs when the sample does not represent the population
Bias can threaten the validity of research findings.
What is probability sampling?
A method where every member of the population has a known, usually equal chance of being selected
This method enhances the representativeness of the sample.
