Quistioning things and not taking things for granted
Seeing things as they really are
Thinking reflectively, productively, and evaluating evidence.
Critical Thinking
Steps of Scientific Method
Theory, Hypothesis, Conceptualize problem,Collecting research,Analyze data,Drawing conclusions,Revise research conclusions and theory
A broad idea or set of closely related ideas that attempt to explain certain observations
An idea that is arrived at logically from a theory, prediction that can be tested
An objective description of how a reseach variable is going to be observed and measured
Operational Definition
Chose to study whether writing about negative emotions and the situations that caused them would reduce stress and make people healthier in the future
Every member of the population has an equal chance of being selectd
Random Sampling
Observes behavior in real-world situations and makes no attempt to manipulate or control situation
Naturalistic Observation
In-depth look at a single individual
Case study
Describes the strength of the relationship between two variables of characteristics
Correlation research
Degree of relationship between two variables
Correlation coefficient
Relationship in which two factors vary in the same direction
