SCIENTIFIC INVESTIGATION
Its the number of steps in the Scientific Investigations
What is five
Psychologists and other scientists share this number of interrelated goals.
What is three?
Differing approaches to the observation, measurement, manipulation and control of variables in empirical studies.
What are Research methods?
When investigators want to determine whether there is a correlation between two variable.
What is descriptive research?
In research, this process helps science identify and purge inaccurate findings.
What is replication?
This is the second step in the scientific investigation
Select the Research Method and Design the Study
This is the first goal in the scientific enterprise.
What is Measurement and Description
One of the basic types of research methods that psychologists depend on more than any other.
What is the experimental method?
When two variable are related to each other, either positively or negatively.
What is a correlation?
This technique is used to make sense of inconsistent research results.
What is Meta-analysis?
The persons or animals who's behavior is systematically observed in a study
Who are the participants (subjects)
This is any measurable condition, event, characteristic, or behavior that are controlled or observed in a study.
What is a variable?
This is the variable that is thought to be affected by the manipulation of another variable.
This depends ONLY on the size of the coefficient.
What is the strength?
This happens when a sample is not representative of the population from which it was drawn.
What is a sampling bias?
These are the procedures for making empirical observations and measurements used in step 3 of the Scientific Investigation
What are Data Collection Techniques
Scientists use this to evaluate understanding, by making and testing this.
What is hypothesis?
The main advantage of manipulating two or three independent variables permits the experimenter to see what.
What is see if two variables interact
This is allowed to unfold naturally without interference in its natural environment.
What is Naturalistic Observation?
In research, when someone gives socially approved answers, memory errors undermine accuracy, or respondents agree with nearly all statements can cause this.
What is distortions in self-report data?
What is whether the color red increases men's attraction to women.
By integrating unrelated facts and principles into a coherent whole, this permits psychologists to make the leap from description of behavior to understanding of behavior.
What are theories?
Psychologists prefer to use this when possible so they can draw conclusions about causation.
What is experimental method?
This type of research involves investigators analyzing a collection case studies to look for patterns that permit general conclusions. But, they are highly subjective.
What are case studies?
This is a research strategy in which neither the subjects nor the experimenters know which subjects are in which group.
What is a double-blind procedure?
